Hello!

I am in need of a generator for my beloved Coleman stove, I believe. The fuel appears to be coming out of the end of the generator but then pooling and leaking at the very bottom of the stove. I’m thinking there must be build up in the generator somewhere. Any help is appreciated.

"I’m thinking there must be build up in the generator somewhere."

Is the fuel leaking when the stove is off? A more detailed description of the conditions under which you experience this might help identify the issue.

Is this while running?  The generator has to get hot to not spit liquid fuel.

Agree with Outlaw.  Maybe preheat generator with a lighter or a torch (be careful - move the flame all the time). Then try it.

Try cycling the pump 40 or 50 times and keep the valve in the OFF position and then open the fuel cap. Do you get a loud hiss of escaping air? If not your fuel cap gasket may be bad or the Schrader valve may be bad. The fuel would drip or leak out because there isn't enough pressure in the stove because it is escaping at one of these two places.

Next, with the cap closed tight, try cycling again 40-50 times and keep the valve in the OFF position, then check to see if any fuel is leaking from the generator where you saw it before. Is there any fuel dipping there? If so, then you most likely have a bad Schrader valve. Fuel should not be escaping when the valve is off.

We mention this, as @zoomkat noted, because there is a Schrader valve core in the valve assembly. This is just like the one in a bicycle tire expect these are fuel rated. I've had a couple go bad over the years.

Keep us posted.

Hi. I did that at for the first example, o did get a hiss of air, and for the 2nd, I did not get any leaks... I think the pump system is still good.

When you say "leaking" in the first post,  is it a slight drip?  or a lot?

Assuming its very slight the genny sounds like it may be plugged,

Try removing it and see if it streams when the valve is opened, 

If so,  you can try heating it to near red hot with a Bernz-O-Matic (Plumbers) torch, and, using pliers, quench it in water.  do this several times.  you should see flames coming out of the ends as the coke buildup inside burns off.  once it stops take the orifice off the tip and try blowing air through it to clear loose debris.  Clear the orifice tip with a wire from a small (toohbrush sized) wire brush.

I just thought of something else  - is the orifice tip loose?  this will cause excessive fuel to drip...

That sounds like a good suggestion. I’ll try that. Now, I’ve noticed on some generators that the one end (where the fuel comes out) is screwed on and can be removed to clean it out. Mine is soldered on, which makes it difficult to remove any build up. (I think that’s the orifice tip you are talking about). 

I’m thinking it must be build up in the generator. I lit it for the first time in a long time and it lit at first before flaming out.. nothing since. Some vapour is coming through, but not enough.. that’s what I believe is the problem.

I’ll keep trying. Everything else seems to be fine.

Do you use camp fuel or pump gas?  pump gas generally destroys gennys over time...

Well 400's are too new fangled for a codger like me but...

Fuel pooling wouldn't indicate a clogged genny. Master of the obvious i am...

Assuming the genny  is hot enough to do it's thang..changing liquid into a gaseous state..and the tip isn't loose or hogged out..could there be an obstruction down stream? Perhaps where air comes in?

@Tracy everybody here is trying to make sure the actual problem is being identified and possibly save you a little money, however, if it comes down to needing a generator, our host has them, here:  https://www.oldcolemanparts.com/product.php?productid=275&cat=33&page=2

Hey!! I got it working!! I am thrilled 🙂. There was a build up in the generator that wasn’t allowing the pressure to get through. Thanks to everyone’s suggestions and help. My little buddy is 25 years old now, and I hated the thought of getting a new one. I looked yesterday, and I did not like the new backpacking stoves in my local camp store.. it looked like they are now an all in one system with the cup/pot that has to match?? Anyway, mine is much better.

It started working after I took the generator off, took the wire out, cleaned it all and torched the end. But good to know there are still parts out there.
