if your having issues then read through this...

if you pump it up until you feel some resistance on the pump then you know its pressurised. if it still wont feed petrol through then the genny is blocked.
if you get no petrol flow then gently open the petrol filler cap. there should be a hiss as you release the pressure. this will tell you the seal on the pump is working and the seal on the petrol tank is ok. if there is no build up of pressure, and no hiss when you open the fuel cap then the pump washer needs oiling/changing.
you can buy a new genny [about a tenner] but always best to try and clean the old one, as youve nowt to lose!

below is a more detailed breakdown of the problems, and the fixes...

if the flame is orange then its not burning "clean", which means a good balance of air and fuel. the blue flame shows its working correctly.
to get it to run clean you need to have;
clean unleaded fuel.
pressure.
working genny.


to check the fuel is clean empty the petrol into a clear plastic [wide mouthed] bottle and look at it. i always fill my stove from fuel container into plastic bottle with a filter funnel. then into the stove.
i add a small amount of redex injector cleaner [from a car shop/halfords/etc] at the recommended dosage. do not overdo it as you will gum up the stove!
[the fuel should just change colour and have just a tinge of pink to it] use 5ml to 5 litres, but no more!

to ensure you have pressure check the pump washer is not split, and smear in some light oil. check the fuel cap seal looks ok. you should feel the pressure build up and it become difficult to pump. then you know its holing pressure.

the genny is a hollow tube that allows the fuel through. as it flows along it turns to vapour due to the heat of the stove and the pressure in the fuel tank. there is a thin wire inside the genny that runs back and forward as you turn on and off. this is to try and de-coke the inside of the genny to ensure a easy flow of fuel/vapour.
it is easy to clean an old genny by carefully extracting the wire and cleaning the gunge off with the edge of a knife. be careful not to dig it in and kink the wire! put the empty genny into a small pan with some boiling water and a spot of fairy liquid. this will clean out most of the residue.
thoroughly dry and re-assemble... sorted.

Fixed the genny in a very simple manner. The wire in the genny has a diameter of 0.3 mm. Get a foot of 0.4mm nichrome wire. It is both stiff enough and hard, and can easily remove any residue block within the genny. Insert it into the genny slowly using pliers several millimeters at a time until approximately 3/4'ths is inserted. Once or twice will do the trick. Good luck!

i managed to fix mine, i undid the retaining nut and pulled the red tap of the valve and on it was a couple of 'o' rings and one of them had split so the fuel must of been coming from there, i had some at work so just replaced the o ring with a new one wiped a bit of oil on it for lubrication then put it back in, i did put some ptfe tape on the retaining nut aswell for added sealent, pumped and fired it up and boom works fine again. however the 'o' ring i used, well im not sure how long it will last due to it being in contact with fuel.

Inside the pump there is a small rubber seal, check that this has not split or perished, also if it has dried lube it up with something oil based. They used to have leather washers in which were much better as the rubber is very thin and breaks easily. Mine kept getting caught and not sitting flush until I had a mess about with it and got it working. I ended up using a bit of butter to lubricate it and it was fine from then on.

Yes, and I have to often re-pump fairly quickly to stop it dying, and then maybe 50 times to get optimum burn.

When you re-pump after just igniting, does your flame die down when you withdraw the plunger??

I have no clue about the valve, however...

It could be the generator. I cleaned the generator on mine and got it working only to have it die on me again the next time I was on the bank.

I then bought a new washer set with leather pump cup thinking that I had fixed the generator and perhaps the problem was somewhere else. This made no difference.

Try cleaning the generator, there are a few methods listed here. If yours is like mine though, a replacement generator could be the answer.

When i release the plunger to apply more pressure, pump again, the flame dies down, does this suggest that the one way valve is failing. Doesn't seem to get the same resistance as when it was new,
got a new leather washer clean primus fuel, and an annoying yellow flame at rear, bought a new valve but cant remove existing, a big flat headed screw type.
Or do you think just a dirty genny?

I`m not sure if it is of any help at all but I have come to the conclusion on my stove that the wafers need stacking neatly for a clean, correctly directed burn. When I haven`t taken care in the past, the pan below the wafers has become glowing hot.

Like I say, it may be of no help whatsoever. Each cooker is so unique, each with their own idiosyncracies.

Pan sizes vary and the kettle is a small one cup jobby and the problem persists.

I'll strip it down again and check out the genny, I have a spare if needed.

Because it fires up and burns well I've never re-stripped it. The bowl has always glowed red as they do but the heat transfer downwards is an unusual development

Could be a blockage in the genny, maybe some dissloged deposits that where left in after you cleaned it. Pump it up again and open and close the valve very quickly, do this a few times and jsut maybe it will clean itself, failing that, strip it and start again.

Just getting my stove out for the winter.

I've had it about 15 years or more ( was the DualFuel now called the Sportster 533) and apart from the first year when I ran it on Petrol, I've run it ever since of Coleman fuel and for the last 9 years or so on Aspen 4T so it's nice and clean.

During it's lifetime I've replaced the generator (after the initial petrol phase)and also replaced the origial pump washer with a leather upgrade mode, which is regularly oiled.

So, it runs perfectly, lovely blue flame. The problem that I have is the bottom part of the stove which houses the fuel tank is getting extremely hot. Now I understand the principle behind the generator heating up the pressurised fuel as it passes over the burner and that's fine as it has an outlet ie it burns in the bowl.

However the bottom beneath the burner is a different matter. It never used to get this hot. There is no fuel leaking from beneath the burner, in fact everything is as should be just the actual bottom part of the stove, the main body beneath the burner box assembly is far far hotter than is safe. The piece of heat retardant material is still in place between the burner box assembly and the main body/fuel tank.

When I go to turn it off like most other people I place my left hand on the shoulder of the bottom of the stove to steady it and turn off the red lever with my right hand, only now I need to wear a glove or wrap a thick rag on my left hand to steady the stove. As I said, far , far too hot for safety.

Anyone had this problem and know a fix?

I recently tried to get my old Coleman working again and after removing the needle and wire and cleaning the generator I got it going. Although I must add I didn`t try the boiling water/fairy liquid suggestion, rather WD40 and pressurised air.

Sputtery flame at first but then it started burning a treat. I let it burn off a full tank which also got rid of the heavy carbon deposits. I was well chuffed!

Went fishing, first morning tried to brew up but couldn`t get the thing going again. When pumping, fuel came out of the pump hole. Couldn`t get any pressure, or at least no hissing sound came out when turning the burner valve lever.

Where would be the first place to look? New pump washer? If so, how do I take it apart to get to it?

i strippped it on the bank, and managed another brew on it but then it give up and so did i. i could run it on lighter fuel if i could get the dam thing to light. ill strip it down later when the kids are in bed. theres a peice of folded foam material under the burner that looked a bit crusty though so its probably this or the genny blocked.

Sound like no pressure. Try greasing the washer before you buy another. If you do need one, leather is better.

no the pump does not get harder it stays the same ,you can see a jet of fuel coming out the genny and the flame stay yellow i would say there is no pressure there .so i will give the genny a clean out see if that is any better if not get a new washer and by that do you mean the rubber thing on the pump?
Thanks

Could be either one of not enough pressure or a blockage in the genny.

When you pump it does it get harder to pump? if not change the washer, if it does then clean out the genny. If you don't know how to there are instructions further down, although I do like the idea of using coca cola. Sometimes you can clear a blockage by rapidly turning the valve from hi to low, you will hear it go as the whoosh is louder if you know what I mean.

That dripping is fuel that isn't being turned into a mist and so dipping out the end of the genny. Not the best thing to have

The drip is from the end that goes under the flame .once i open up the tape after pumping it starts to hiss then you can see dripping from the oppersit end to the tape .

Check the leather seal in the generator normally this will wear and split during use.

Been using these stoves for years in the army and they are very good. I have tried different fuels and they tend to clog up the pipes. Using the colemans fuel I do not have this problem. Also if leaving the cooker unused for long periods the fuel becomes unstable so good practice is to empty when being stored.

If experiencing problems with burning or leaks it mainly was the pipes being clogged with different fuels, quick fix was to strip the pipes and run through with cleaning brush and soaking the wire. this tends to fix most of my problems.

hope this helps, it worked for me.

it might be the rubber seal on the fuel filler cap has perished. try swapping the cover with a mate and try that. . maybe some ptfe tape on the thread might effect a temporary repair as a tester.

HAving trouble keeping pressure with feathlight stove, Got a new genny on it, plus changed rubber pump washer to a leathrer version.
Do the following.
Pump 25-30 times.
Ignite
Pump 25-30 times.
Looses pressure after a minute. Don't want to keep re-pressuring every, any ideas what's wrong.
By way run on coleman fuel.

When I withdraw the pump with finger over hole, the pressure decreases (flame dies),does this suggest the tank valve is leaking? If so is this repairable?
Update, think I have fixed this by removing inner stem placing oil around the thread to form better seal/gasket.
Fingers crossed

colemans are never good at lower heat settings. they may splutter a bit, or as yours does, be either full on or off.

Well after having a good read of this thread I just took the Coleman apart and give the generator a good clean inside and out (took the wire out and give that a good clean too), seems to be running like new FOR NOW! Hasn't run like that in years!
Its now in the rucksack ready for the early morning brew test tomorrow when I get down the Pit!

Thanks all who have posted in this thread, all the info really helped

Having real trouble with my sportster 553, at first it would light then go out after a few seconds......quite annoying when trying to have the first brew of the day, now it doesnt realease any fuel at all and wont light (and yep theres plenty of pressure in there!) its probally done 300 nights without any repairs etc since new before I started getting problems with it but as im useless mechanically I havnt got a clue! Im guessing theres a serious blockage somewhere!

Im very tempted to just chuck it and buy another!

Any ideas?

Just hook it out with a stringer needle or similar , preferably an old one if you dont fancy petrol residue on one you use for baits . hook behind it and pull gently,

Do you mean the non return ball bearing valve Richard?
If so i think the spring goes on them and you have to replace the whole generator.
I rang up coleman and they gave me a parts department they use in the uk.
Im sure the company i used is Johncross. If not try oldgeezer on the forum is pretty clued up about coleman stoves.

Try this website for spares, Im not sure if its the cheapest but the prices seem reasonable.
Johnscross spares

hi guys, been having problems with my stove for a bit and decided to investigate, found the generator was partially blocked so took it off and soaked it and was quite impressed at the amount of crap i got out of it to be honest. now when i came to put it back on somehow the valve inside the generator has slipped back up inside and i cant seem to get at it to get it out.






any ideas guys?

do i need to get a new generator and if so where is best to buy from? and how do i stop this happening with a new one.

many thanks in advance

Well, the check valve got here alright, but it proved impossible to take out the old one, so I'm pretty much stuck with a brick. I tried car mechanics and metal shops around the village we're at now, none of them could extract what seems like a totally stuck valve.

Field serviceability... not impressed.

Hi, just had the same problem. I f you take off the pump mechanism, the bar that slots into it may be jammed. It can be freed carefully using a pair of pliers.

Thanks for the note.

I contacted Coleman UK and a quite helpful chap had the following to say:

[...]your problem is the check valve ( one way valve ) which is in the bottom of the pump cylinder these do normally perish over time ( i.e. years ) these cost 9.99 & can be replaced by using a 3/4 " metal file & a pair of molgrips simply unscrew & replace

I ordered the part (which btw appears to cost 25% of that in the US...) and will let you know how it goes when I receive it.

Cheers

Alex

Hi Alex it sounds like the little non-return ball bearing is not working on your stove, i had the same problem with my Duel fuel tilley lamp but i just put it down to genral wear and tear of the leather seal splitting, after buying a new generator and leather seal they lamp worked fine. I know they say you should try and give it 30 plunges to prime this and to be honest it wouldnt work for me. I found it hard and expensive to obtain spares from coleman's but did find a shop on Ebay which sells spare leather seals and generators. If not try Gerry Oldgeezer on the forum i know hes pretty clued up with the coleman range

Hi all

Ive cooked at least 100 meals on my Sportster 533 (which Ive had for 3 years now). Yesterday I went to bed with a cold sandwich.

Symptom: Its impossible to do the first step (pump 30 times to build pressure before lighting the stove), as the pump will not even accept being pumped ONCE with my finger on the hole...

With the hole uncovered the pump appears to move in and out as normal.

I have drained the fuel, left the fuel cap open while pumping, no difference. Its still impossible to pump even once.

I took the pump out to have a look and this is what it looks like: Photo of pump

As I am "in the field" (cyclo-touring in Chile) I dont have proper oil, but I sprayed WD-40 all over the pump parts and reassembled to no avail.

1. Is this seal broken? The center part looks quite regularly shaped and thus normal to me.
2. What else could be going on here?
3. If worse comes to worst and I have to get spare parts where do I order them from? Coleman USA even though the stove was purchased in the UK?

Cheers

Alex

I have a new gen for my sportster but it's dfferent to my old one, in that the end which goes under the burner and is fixed in place by the plate and 2 screws, is round, whereas on my old one it's hex.

I'm assuming this won't fit, and don't want to open the packaging as it would prevent me returning it. My stove is getting on for 20 years old so maybe I need an older version with a hex nut, or maybe the round one will still fit - can anyone clarify please?

Sounds like your generator again. I have experienced similar issues and reverted to cleaning everything out by using the Coleman fuel every five or six fill ups. In between I use normal 2 star with redex as suggested by BM in post 1000. I assume you have checked that the "L" shaped brass tag on the end of the wire is correctly positioned in the valve as well??

Incidently if you really want to sort out your stoves go and read post 1000 it is very detailed and contains some excellent advise.

Ok my sportster 533 has a problem, when I turn the red lever it's a bit temperamental and fuel sometimes comes out properly and then other times it only comes out slightly?! I have stripped it and cleaned it all up but it's still the same! Any ideas people?? Gen was only replaced about 6 months ago!!

i have the same stove and i contacted coleman in the states to find out how to get my stove serviced they told me how to do it myself its really simple just be careful when you take it apart its a little fiddly getting the fuel bar off but once you have in bits its simple to clean and will save you a small fortune taking it to a shop to do the same job they told me its just carbon clogging the holes so just use a toothbrush on all the bits and a little petrol and job done hope this helps a little
just 1 thing DONT take out the rockwool inside you wont get it back in just clean off as much crap as you can

My coleman is occassionally emitting flames from under the burner unit, and also sometimes when it is switched off I can hear fuel escaping.

Before I take the thing to pieces and work out that I don't know what is wrong with it can anyone thing of any likely scenarios?

It is very erratic, it will be fine for ages then do it a few times in sucession. It nearly got booted into the lake on Friday night when the whole thing errupted in flames. Had I not been so desperate for a brew it would have done

Releasing the pressure stops the fuel leaking (obviously), is it likely to be something to do with the lever assembley not pushing the wire all the way back through and allowing fuel to escape? It sounds like it is coming from under ther burner unit though which makes my first suggestion near enough impossible.

It's between posts 76 and 1158 (don't ask me why)

if your having issues then read through this...

if you pump it up until you feel some resistance on the pump then you know its pressurised. if it still wont feed petrol through then the genny is blocked.
if you get no petrol flow then gently open the petrol filler cap. there should be a hiss as you release the pressure. this will tell you the seal on the pump is working and the seal on the petrol tank is ok. if there is no build up of pressure, and no hiss when you open the fuel cap then the pump washer needs oiling/changing.
you can buy a new genny [about a tenner] but always best to try and clean the old one, as youve nowt to lose!

if its not burning "clean", which means a good balance of air and fuel. the blue flame shows its working correctly.
to get it to run clean you need to have;
clean unleaded fuel.
pressure.
working genny.

to check the fuel is clean empty the petrol into a clear plastic [wide mouthed] bottle and look at it. i always fill my stove from fuel container into plastic bottle with a filter funnel. then into the stove.
i add a small amount of redex injector cleaner [from a car shop/halfords/etc] at the recommended dosage. do not overdo it as you will gum up the stove!
[the fuel should just change colour and have just a tinge of pink to it] use 5ml to 5 litres, but no more!

to ensure you have pressure check the pump washer is not split, and smear in some light oil. check the fuel cap seal looks ok. you should feel the pressure build up and it become difficult to pump. then you know its holing pressure.

the genny is a hollow tube that allows the fuel through. as it flows along it turns to vapour due to the heat of the stove and the pressure in the fuel tank. there is a thin wire inside the genny that runs back and forward as you turn on and off. this is to try and de-coke the inside of the genny to ensure a easy flow of fuel/vapour.
it is easy to clean an old genny by carefully extracting the wire and cleaning the gunge off with the edge of a knife. be careful not to dig it in and kink the wire! put the empty genny into a small pan with some boiling water and a spot of fairy liquid. this will clean out most of the residue.
thoroughly dry and re-assemble... sorted.

You could try removing the generator pipe and simmer it in a pan of water with a good squirt of fairy liquid for about 15-20mins, it usually helps clean the carbon deposits off the inside of the pipe, but there's no guarantees......otherwise a new genny costs about 13 and takes two mins to fit.

Flash, I'm presuming there's fuel in it, so it sounds like the generator might be blocked.

Can anyone help??
Just got the coleman out and havent used it since last year.
I pump it full of pressure but turn on the valve and have nothing coming through, not even a hiss.
Any ideas?
Thanks.

DO NOT POUR WATER ON IT !!! when its cold just get a small spanner andGENTLY tighten all the nuts and bolts and you will find it stops leaking.The nuts are only factory fitted and loosen in transit.If you turn it down to minimum for one minute before you turn it off it will light better withonly 10-15 pumps

I`ve had Coleman`s for years and I bougt some new gennys in the past because I`d used unleaded fuel in them and they got clogged. Coleman fuel in the Uk is expensive like 6 just for a small tin.

I use Coleman Fuel ONLY now and get it for 6 a LITRE from here ...........
http://www.askari-fishing.com:80/__WebShop__/product/fishing/camping-boats-1/camping-cookers-heaters/coleman-fuel/detail.jsf

My advice - get some now.

Hope this helps.

Russell (aka Baron)

PS: Make sure you always `regularly` put a drop of oil down the pump cup hole (when you get back from a trip) then it`ll work a lot easier and the washer (leather or rubber) won`t dry out either. Oh yes and it also helps if you put two small drops of the old REDEX in with the complete fuel fill (you can get a tall neck small bottle from Halfords) it`s the stuff some guys still put in motorcycles as an `upper cylinder lubricant`. Try it, it really helps.

Simple! release all the pressure first!

Take the 2 screws out of the plate that the generator sits in at the spout end.

Undo the nut at the valve end and remove the generator.

then to replace, put the spout end in. in the valve end is a little bent piece of brass, this slots into the valve stem, then line it up do the nut up hand tight and tighten with the applicable sized spanner. Replace the support and replce screws.

Before you light that stove, double check that the nut is on nice and tight!

Genny comes complete, small wire included. As for the low setting problem: A guy did post on this thread suggesting to add an extra 'frilly ring' to the rings were the flames come out, stating that it improved the control on his coleman. If you read back a few posts its all there.

Are you to de-pressurise before storage after each fishing trip? Mine makes my bag smell like crazy. I have turned it off and the red lever is in the closed possition.

if its low on fuel then there is more air space to pressurise, so there is more pumping needed. if you fill to within a couple of centimetres from the lip it should pump up quite easily. as the fuel level drops it needs more pressure.
even a full stove needs a good pumping prior to lighting. you should pump it until you feel its getting very tight. this is the build up of air pressure inside the stove.
if the flame starts to turn slightly yellow it needs re-pumping to restore the fuel/air mix.

no need really as you could just soak it in a plastic tube, we only used to do it that way with the exhausts because of their size.

You can get it from any hardwear store or somewhere like B&Q, its dead cheap so you shouldn't be paying over much 2 for a tub.
I used to plug one end up then just pour about 1 cup full of soda into the exhaust and pour in luke warm water because if you use hot water it will shoot water out the pipe or the gas it gives off (you can weld with it) will burn your lungs as it is a little bit toxic .

might consider that if none of the previous can bring a genny back from the dead.
how much caustic to how much water? do you have to add the soda to hot water to get it to dissolve?
and where do you get it from?

do you mean;
remove the wire from the genny, then soak in a caustic soda solution, to help break down the carbon deposits?

Just as an idea, we always used to used caustic soda to remove carbon from our motorbike exhausts. 2 stroke engines burn alot of oil so you had to clean the exhaust 1-2 times per year and caustic soda always worked and was cheap.

whats it been run on, aspen?
sorry, read your post again!

maybe your not whacking enough pressure into it. although the aspen is supposed to be cleaner [never used it] it will still need the right fuel/air mix. the redex will de-carbon it, and the full pressure burn/hi heat will clear the soot/coke.
mine burns red hot, the outer ring glows

start with emptying all the old fuel into a clear bottle. this allows you to see what ***** has been going through the stove!
add some new fuel [normal unleaded] with a tiny bit of redex in it [5ml to 5 litres]

pump it up to full pressure, and then light. as soon as its burning fully and glowing hot, turn on and off a few times. tap the genny with the back of a large spoon, to help dislodge any carbon in the genny.

turn on and off a few times [rapidly] and see if its now burning cleanly. make sure your using it pumped up to full pressure.
if your still struggling try reading all the previous info.

Great info. Cheers everyone.

Have a double burner and had issues with a leaking on-off valve as dripping fuel was collecting. Reckoned it was a blocked genny causing a back up of pressure escaping out of the on-off valve - confirmed by a quick phonecall to the Tackle Box (Coleman spares and repair centre).

After stripping down the genny assembly and boiling it in water for 15 minutes then rebuilding it and hey presto...
...ROARING BLUE FLAMES on both hobs. Just like new!

Thanks to this thread I've saved 15-25 on spares + postage charges .

when you put the pump or plunger back in make sure it locks into the inner pipe which locks it up to keep the presure in as in when you pump it 20 times you always turn it to lock it when pushing it back in if it s not gone back properly you loose the locking of system for the pressure

there could be the slightest imperfection in the washer, maybe in the centre?
to eliminate the chance of it being your washer try swapping over the pump assembly with a mates, just to test your stove. if it works with the replacement then it must be your washer. if it needs replacing then get a leather one.

if it aint the washer...

its just the way they are.
never good for gentle heating. the best compromise is to get the stove really hot, then it will turn down to a simmer for a while before it starts blowing out yellow flames.
i boil the kettle for a brew first, then put the frying pan on for the bacon. if you do it the other way around it gets messy.

not taken one of them apart... anyone???

i would imagine its the same principle as the sportster. the wire is connected to the on/off lever, not the jet end. the jet is a fixing at the other end of the genny, and is not removable. you can clean the outside of the jet. just a gentle scrape. this will help the flow of the vapour across to the burner plates.

take the pump assembly apart and look at the pump washer. if its the plastic washer check for splits around the edge and in the centre where it secures to the central shaft. if its damaged it needs to be replaced, and its better getting a leather one.
if the plastic one looks sound then it may have contracted. smear lightly [front and back]in some cooking oil. this will slightly expand the plastic and may be enough to give you a decent seal again.

Got a problem with my Coleman. Seems like there is a problem with the pump as i can't generate any pressure no matter how much it is pumped. The pump feels very 'loose' when pumping and you don't have to apply any pressure when pumping it.

Any ideas? It is a case of buying the pump repair kit and replacing as necessary?

some will be crap from in the fuel or container, and the rest of the sooting in the genny will be fuel that is left in there from when the stove is turned off, and a trickle of fuel is still flowing. you must have seen some that almost refuse to turn off! the heat will dissipate from the genny,but some fuel will collection the genny, hence the yellow flame on turn off. fuel is being burnt, but heat and the extra air is no longer present. the is almost certainly what is coking up the genny. its just like a carburettor on a car that is running with a poor fuel/air mix.

But I think that the idea was to burn off the deposits in the genny, the result was worst case.

Makes sense though, the better your fuel is vopourised then surely less is left behind to turn to gunk, or is that just crap from the fuel/container.

and the fuel now flowed freely - albeit exiting from the new holes! so with more care this may well work.


i had read that bit from the link. i think he's actually refering to knackering his genny by burning through the outer and burning extra holes for the fuel to flow out better [irony?]

That kinda ties into what the guy says in the further reading link.

Maybe the extra heat is conducive to a better fuel vapourising leaving less in the genny?
I have a few spares, once I get the genny unblocked I will give it a go.

From the link:-

First, heat was suggested by a friend. This could be a goer, I remember my dad heating up his motorcycle exhaust with a blow lamp or oxyacetylene to clear the carbon blocking the flow of gases.
First I tried placing it on a domestic gas cooker ring. This successfully heated the generator to a red glow, but no difference in the flow of fuel was achieved. Next I tried a gas blow lamp, this time the generator was glowing a brighter red. Unfortunately I went a little too far with this method and burnt some small holes in the brass tubing. I was able to recover some ash from the generator, presumably from the burnt carbon deposits I was attempting to remove, and the fuel now flowed freely - albeit exiting from the new holes! so with more care this may well work.

never heard of this before, Simon. might give it a try when i next have a stove in bits...
interseting idea.
how many extra burner rings did your mate add, and did he have to change the screw [the one in the centre that retains the burner rings] for a longer one.

I have a little tip if you havent tried or heard off for the colman 533 petrol stove

A freind of mine doubled up the burner rings and now it runs like a dream i can turn it up or right down and cook perfect every time mine is brand new and it wouldnt ever turn down low so a mate of mine added more plates just under the generator and it runs like a dream.

Think they cost me a 10 but worth every penny

Hope that might help some one out good luck ... Easy to do as well

Yes, cover the hole with your thumb as you pump.........It won't build up the pressure if you don't, surley?

Have I just fell for a trick question?

Dave, another easy way is to remove the wire and squirt carb cleaner down the pipe, then put the cable back in and move it back and forth, then clean it out with a air compressor, works every time

maybe the tube if fractured and you wil need a new genny. if you have checked the nut that seals the genny onto the on/off switch and thats solid it may be worth undoing it and having a close look at the end of the genny where it fits into the nut.

if all else fails its going to be a new genny.
