My brother found this coleman 500 in the woods. It was made in 1946. He said the stove was partially buried in the sand. It was near the ocean and the salt spray had done a number to it. I was afraid that the rust would seize it up and it wouldn't come apart. So first I tried to see if it would work as is. I soaked the pump in oil. Then I was able to get it to pump up. I opened the valve and a fine mist came out, but it wouldn't light. I emptied the tank and this is what came out. I rinsed the tank out with white gas and the white gas floated on top of what had come out of the tank. My guess is that the tank just had water in it. I was able to get the stove partially apart and I soaked the generator in vinegar. I broke a screw that holds the burner to the tank. I had to use an easy out to extract it. I replaced it with a new screw. After I put it back together it ran, but not that well. I put the burner parts in a electrolysis tank because I thought it might help stop the salt water from attacking the steel parts. I was able to get the burner apart and I was able to clean between each of the burner rings. I put the stove back together and it looks much nicer now. It also runs much better. This is the second Coleman 500 I have owned. The first one I bought 20 years ago and the members on this forum helped me get it running. I haven't been on this forum in a long time, but i appreciate all the helpful information that it contains and all the help I have received in the past.
