Hello all. I have a colemans unleaded lantern. I have had it for about 15 years. It hasn't been used for about 3 years. I got it out this morning to give it a test run and it wasn't impressed. It had good pressure, but it wouldn't s tart injecting fuel till it was on 'full'. It wasnt a very consistent flow either. Then after a few seconds it basically just petered out. Checked pressure again and it was fine. I do remember that even when I used it 3 years ago it wasn't working all that well.

Can someone tell me the basic fixes for an unleaded lantern?. Replace or clean jet?. It still had some old fuel in it which could be a big part of the problem too. I'm guessing that I need to clean the whole system out but not sure where to start. Any help would be appreciated. thanks. Grant

If it's anything like a kero lantern (same principle) replacing the generator (the thing with the jet in it) should fix it. There's not much else to them.
One tip though, check the pipe where air enters the system to go up to where you tie the mantle. I've had mudwasps build nests at the entrance of the tube and restrict air flow.
The only time I made a mistake was when I thought I was wrong, but I was mistaken.

Hi Grunta1970

Ive restored a number of both lanterns and stoves of the coleman variety.
There very basic, well designed and servicable units that will give years of service.
have a 1965 lantern as a normal camp light, and a 64 twin burner stove.
Both work as well as the day they were first made.

2 things to look at.
First is the generator on the top of the valve, the long thin thing that has the fine mist of fuel come out the end.
Be carefull with the tip, as it has the fine wire that cleans out the tip of soot etc.

The other is the emulsion tube, which is inside the font/ bit you fill with fuel.

unscrew the top assy from the font, and check for contaminated fuel or any foreign material in the pickup pipe and its filter.
Often if left with stale fuel, these clog up and cause poor light, pulsing light, yellow light, poor controlability etc.

http://www.coleman.com/Parts/140/dual-fuel/229-700/dual-fuel-lantern

if thats not your model, just find the one that is, there is an exploded view on that page.

Give both top generator and bottom tube a good clean out, drain and rinse out the font, and fire it up again.

I would think by then, you will have a great working lantern again.

Let us know how you go.

ps, also google coleman lantern restoration, quite a few yank sites with blow by blow descriptions and pictures of how to go about it too.
Worth a cup of coffee or two to find.

hope this helps

Thanks all. Yeha, i figured it was probably the generator but wasnt quite sure. If i was to purchase the generator, do they come with the jet nozzle or is that separate?. Also, the only place I can find a generator for that model is from a guy in usa on ebay, cant find anywhere else, not even on colemans site. lantern model is 282 700 and generator part number is 285 5891

Before you go and order from overseas.

my guess is that its the pickup/ emulsion tube thats clogged with either gelled or varnished fuel.
Then what can has moved up and blocked the generator tube and end.

Wont take much to remove and give it a good clean out.

Same with the generator, not hard to undo the nut, and carefully take out the inner part, and clean the tube and reassemble and see how it goes.

Ive restored a few generators before by sooting up the outside, and then burning off the soot with an appropriate flame, then cleaning out the burt off crud from inside the generator tube.
Burning the soot off gets you to the right temp to burn out the crud that can accumulate inside it.


Shouldnt take more than an hr to give it a basic clean and blow with some air.

For clarification, in your case i dont see the need to burn out your generator tube, just used that as an example that you can pretty much fix what most would replace.

If yours has sat for 10 years, my guess is stale fuel, and thus mentioned blocking up of pickup/ and generator.

A pipecleaner up the generator tube once its been diss asembled and its inner bits removed should be enough to clean it well.

That link will show you pretty much what you need to do.

grunat1970 - Todays unleaded fuel goes "off" much more quickly than the older petrol varieties. It leaves nasty deposits, gums and varnish when it evaporates. Don't leave any petrol in the lantern when it's not being used for camping.

Cheers - Ron.

I have had to replace the generator twice in mine years ago but I now only use Shelite as its cleaner. Sounds expensive? Not really as they are very efficient.
