My Coleman peak 400A has an internal coil in the generator not like yours. The generator was completely blocked with carbon due to using unleaded fuel. I found the following information on another site not sure we're now. It suggested boiling the generator in a mixture of vinegar and salt, having tried other methods, we gave it a go. We found that carbarator cleaner spray was also very useful. After several false starts and a lot of patience, nashing of teeth and pulling of hair, threats to hit it with a hammer I'm very pleased to say it cleared works fine and is only having Coleman fuel in it in future. It took several sessions. But saved us having to replace it. Hope this is helpful.

I'd say that's from more than 20 years old, mines from the early 1980's and the very same design. I also have a Feather 400 and that is about 20 years old. Thanks for the video, it was very helpful. In all these years I've never cleaned my 400A. It is working properly again but I do need to replace the pump.

Yes that stove in the video would be from 40 years ago, or more, not 20. If you have never cleaned yours, did you always run it on Coleman's 'white gas'? That keeps everything cleaner (generator tube) though I would be surprised if your fuel tank is not dirty after 40 years. Using unleaded petrol, I have had to replace the generator tube a number of times as it gets clogged - the early tube design (mine) is worse for that. I found that as well as dirt, my tank had hard flakes of something like plastic inside, I guess some sort of lining originally used in the steel tank, which cracked and disintegrated.

I love this.

do you know where I can get a new generator for my 400a stove ?

what is the gen wrapped with? Does it help?

I cannot speak for the video maker's results, but mine were not what I would call successful. It's intended to add surface area to capture/retain more heat from the flame, possibly to use kerosene or diesel fuel, or perhaps extended low simmering. I have done this a few time to different stoves and found it only helps a little and has some negative side effects. After not getting satifactory results just wrapping it like this one, I actually silver brazed them completely on to the generator to ensure full contact and maximum conduction. The results weren't much different. But that was MY experience. A sample size of one does not a data set make. I didn't take timed measurements and nothing was scientific. I just wanted to try something that seemed like a sure thing. I was disappointed with my results. Did this on a 425 suitcase stove, a 502 single burner, and a 550B, all in hopes of true "multi-fuel" capability. Not so much.. haha! But that was one guy's experience. It did help low simmer, but took longer to settle down on lighting, I'm guessing due to the added mass to heat up. If they were thin fins instead of relatively thick wire, I'm still convinced it would work. Just not worth the effort to me. That would be MUCH more difficult than wire.

Why do you have wire wrapped around the generator?

I imagine the wire wrapped around the gen tube is there to hold heat for longer. I don't think this would make any real difference to operation except if you were were turning the stove off and re-lighting it in the next minute or so, but even then, does it hold enough heat to make re-lighting significantly easier?
