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 holding 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.

A tip i tried was to mix a little white spirit in the unleaded, i have tried it and it burns blue, would it work if i just used a white spirit?

Hi there. I have tried the washing up liquid trick a few times but with no success, any ideas on getting the gunk fully out?

I use two drops of red X in a full tank every time and have never had a problem.
Got a problem coleman, getting pressue, cleared genny. Reassembled, however once lit petrol leaks from genny attachment above on/off lever. Have tightenedd but now won't even light.
Any ideas???

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.

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

nice one, Pete
nice one, Pete
just a quick question , when pumping up are we supposed to cover the hole in the pump or not?? cheers
In reply to Post #14
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?
