Ok, I found my carbide gas generator. I thought it was all there, but was in sad condition. Had been coated with something, and I have it soaking in ammonia, which is breaking down the crap on it. It looks like it will polish up great.
It is a Gray and Davis generator, and the on/off valve is stuck. Also I cannot figure out how to get the top apart to get to the valve from the inside.
Is there anyone who repairs or rebuilds these things, or who can tell me how to get it apart? I don't want to attempt anything for fear of damaging it, without instruction.
