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.

Leather washer is much better for building pressure, oil with olive oil. Buy from ebay.

If the seal washer is rubber can it be replaced with leather? Also is there a good place to order spares like this?

hi tom, had a similar issue last year on a coleman sportster stove basically there was hardly any fuel getting through and the generator was blocked, I got a replacement generator of ebay I think? cost was around 20.00
it was easy to fit the new generator myself and sorted the issue for me,however this was the only issue mine didn't leak from burner?

Yes, sounds like the genny is blocked. This situation is scary with unleaded fuel p*ssing all over the place, at least with the colemans pure fuel you can shake the flames out if it gets on your hands, etc.
I know the tackle box do service Coleman stoves, I had some joker put sugar in my tank on Darenth, years ago.
Be careful with it

Hi all.

Just bought myself a Coleman feather off of good old eBay and cannot it to work for the life of me. From reading through here it sounds like it could be he generator that's blocked. It pumps up ok (found that out by opening the fuel cap while pressurised and covering myself in fuel), but when opening the valve only a tiny bit of fuel comes through... Enough to light it but only for a matter of seconds before it fizzles out. The second bout of pumps have no effect. Does that sound like the genny to you's in the know?

Unfortunately it doesn't end there... Fuel now seems to be leaking from somewhere around the Burner itself. Checked the seemingly common areas (pump and fuel cap) and it's definitely not them. This has resulted in a couple of fireballs and a right panic trying to extinguish the ******* with my feet before it erupts.
