A friend emailed me and asked me if I wanted this Coleman Mil-Spec. Well, I hemmed and hawed... and said "oh hell yeah!" So I picked it up and all I had to do was replace the cap gasket. It lit right off and it is loud! Someone along the way replaced the original knob with what looks like a screwdriver handle. I'm going to leave it because it's part of it's story.
A 1975 coleman I guess? You got it running at once. Mine is a bit shy with lighting, needs some time. Roaring is the right sound. Well done Matthias
