Hello all. I have the above mentioned stove. It was going fine up until a couple of months ago, now Im having problems and wanting to know if anyone has an answer for me.

Once it has been primed, I turn it to on and a highly visable mist of petrol wafts up and out of the burner. It has never done that before. Normally you would just hear it hissing when it was turned on but no visable petrol mist. Does anyone know what might be causing this?. Thanks. Grant

G'day Grant,

Been using these stoves for about 20 years & replacing the generator always gets it running like new again. If your handy at repairing things you can give the generator a new lease of life by dismantlling it & using some fine wet & dry to remove carbon build up from the long pointed centre spindle of the generator.
In reference to the generator I mean the long tube assy that goes from the control knob to the vapour chamber on the R/H rear of the stove. It's threaded into the boss on the back of the control knob.

The stove will perform for much longer between servicies if you use a small amount of injector cleaner with the fuel & DON'T use Ethanol fuel.

Cheers
Stu

Stu,

I've been using premium unleaded in mine for years, now I'm living in a town that doesn't have premium. Its been burning pretty poorly ever since - smokey orange flame. Shellite burns well but its pricey around here.
Would i be right to put some injector cleaner in the normal unleaded to help it run cleaner?

thanx in advance.

Yea the injector cleaner works fine in regular unleaded.

It is a preventative measure though rather than a fix. If the generator is clogged up with carbon you should dismantle or replace it to get it working properley again.

Do you guys have that OPAL fuel out there?
Never tried it in my stove. My daughter has borrowed one of my Dual fuel stoves for a trip up to the N.T. & is using Opal in it. Be interested to see how it is when she returns.

That's interesting. The last trip I used the stove was when I took my bike across the great central road in feb, only had opal there, for the bike and for the stove. That could be my problem

Well I broke the fine tip off the generator while dismantling it. Cleaned the spindle - but it wouldnt work.
Then I pulled out the spare generator I've been carrying for 10 years - fitted it - and its too long, its for the 414 not the 424. Doh!

Lesson learnt = if it aint broke - dont fix it.

It looks like it campfire cooking this weekend :)

Whoops. That can't be good.

I have a 414 & 424 & your'e right different length generators. Hard enough to get new ones in the cities let alone out in the bush. Looks like you might have to order direct from Coleman & get a new one posted out.

If it happens when you turn on the griller, it could be a case of 'Grillers In The Mist'.

OK, I'll get out of your way now.

hi grunta1970,
try using white spirits same as shellite but that is brand name, have used white spirits for years and have had no trouble at all plus you have no smoke and it burns hotter.

Yeah, I should really use a cleaner burning fuel than petrol, but petrol is practical when I'm out traveling around on my motorbike, I can just syphon a little out of the tank when needed, saves on space.
