Coleman unleaded lantern

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.

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.

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

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.
