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

Just stripped the whole stove down and cleaned every part. I can get some pressure now - enough for it too light but can't build it up for a nice blue flame. Think i'll keep playing until i suss it out.

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.
