    So I picked up a nice 2/81 Coleman 502 for a good price. Here are the pics! I put some fuel in it from one of my other stoves and it lit up right away. Took and decided to do a boil test. After 17 minutes and with 1 litre of water, I couldn't get it to a roaring boil. Maybe I was doing something wrong? I did this out on my deck, not much wind, outside temp was around 14c. I took a couple video's of it as well and I'll try to get them posted!

    LINK to 2 video's. Listening to flame, it seems to fluctuate a little bit while running.

    Looks good!

    Your flame looks to be barely at a simmer, it should boil a liter of water in a few minutes.

    I had the same issue with my 502 when I first got it. Made sure it was sparkly clean inside, didn't help. Pulled generator, plenty of fuel coming out of the generator connection but not out of the generator. Eventually a new generator fixed it right up.

    I had both valves fully opened up. I just got it and wanted to see how it would do before I started pulling it apart. That is my next step, pulling it apart and giving it a good clean, checking the generator, etc. And when it was running, I pumped in a bit more air, just to make sure it had good pressure.

    Well, I ended up taking the thing apart! Amazingly the burner base came out fairly easily. I thought I was going to have a lot of problems with it, but nope. But under that the screw head were quite rusty as well as the plate the screws were holding. The burner rings were a bit stuck together. The inside of the generator looked clean when I shone a flashlight into it as did the feed tube that goes into the tank. Once I removed the collar from the tank, some of the paint was flaking, which is too bad. I am going to leave the tank alone, just wipe it down gently to make it shine again.

    I noticed you said you had "both valves open". There is only one valve on a 502. The lever with the red knob on it controls the pricker to clean the jet. Make sure it is in the correct position or it will throttle the fuel flow.

    I’ve given away a bunch of 502’s as gifts, still have five 502’s on the shelf,,, even have a 501 out there. Do really like 502’s, but I’ve never had the nerve to take one apart...

    What CH Bill said.

    And.....you can add a lot of pressure, keep pumping. If font half full, give it 30 pumps to start, then after warm, another 20 or so.

    And.....wind will really affect a 502.
