Hello, I found a Coleman 502A Stove. This stove is new to me because I have never seen one of these before. Now I do have several 502 stoves, but I didn't know Coleman made a 502A. The stove looks much like the original 502, but uses the same generator as the Coleman 400A Feather Stove. When I started checking this stove out I found the generator was plugged and also the pump was shot. I replaced the generator and used a different pump that uses the leather cup instead of the neoprene pump cup. When done with the fettle the stove fired up well with a lot of yellow in the flame, but the flame turned a nice blue after it ran for a while. This 502A does very well on high and mid range and does simmer, but is very touchy to control the simmer. Pictured included enjoy.
