    Hi,

    I have a couple M1942 stoves. The one on the right of the photos I got yesterday. I replaced the pip and the cap seal. I took out the screen inside the generator and soaked it for a bit in some solvent. I only had rifle cleaning solvent, so that's what I used.

    It is really clean on the outside, but as you can see in the second photo, it doesn't burn as well as the identical stove on the left.

    It has a small blue flame, and barely is able to get the burner red. The one on the left puts out a lot more heat.

    So, a question to all the stove pro's out there: What do I need to do to get the one on the right to burn as good as the one on the left?

    Thanks

    Run it and let it burn itself clean.

    You say you cleaned the generator screen with solvent. Did it come out completely clean, just a nice transparent wire mesh?

    I don't use solvent to clean my mesh screens. Instead, I heat them in a stove flame, gently, to dull red (don't overheat, you can burn it). Once it cools, the remaining ash can be gently brushed off the screen, it gets re-rolled and reinserted in the generator.

    Check, before reinstalling the screen, that the generator's jet is good'n'clean. Should be able to see light thru it.

    Nice thing about having two is that you can start swapping parts to see if it is something simple like the pump gasket or generator. But I agree that running clean fuel for a while is worth trying. Also, another good way to clean up a brass screen is to unroll it and heat it with a propane torch.

    I just received one M1942 myself and was thinking the same thing about the output. I will have to try these helpful tips as well. Thank you.

    I kind of wonder about KARMA. All the Military and .gov stoves I have, (4 or 5) all run like ICBM's on lift off and have done since I acquired 'em. All I've ever done is dump the old fuel, rinse the tank with a couple ounces of meths, dump that, then put in half a tank of fresh coleman type fuel and light up. I've taken a few on Scout car camping trips and the kids have always been mightily impressed. It's most gratifying to see young'ns grinning while watching what looks to be an imminent explosion.

    The .gov stove I like best is the Coleman 530 variant from Civil Defense that has the four feet, quite stable with those, it is.

    So you're saying that I have bad KARMA? My stove is running poorly because the universe is doling out punishment for some past misdeed I've committed? Do you perhaps know of something specific I've done to offend the universe?

    You mean the Coleman 520, or is there something I don't know about? :-s :-k

    Hoppes #9 gun cleaning solvent contains Kerosene. Would that be part of the problem?

    It wasn't Hoppes 9 that I used. It was Ultra-Klenz by Gunslick. But I let it burn quite a long time and it did improve a little. Then I took off the jet and used the spare cleaning needle to really clean it well. Now it burns a lot better. I'll put some photos up later.

    These posts were very helpful. Thanks.
