This is my first post to what looks like a great forum. I have an American Camper propane 2 burner stove (Model 1080 I believe) that my son and I used camping many (58) years ago. I recently re-discovered it in a forgotten box in the attic. Thought he might like it now, with a family of his own. Unfortunately, it leaks propane badly around the shafts of the burner controls. On disassembly, each burner valve has a very small rubber O ring, which I think is just the valve shut off seat. Then there is what I would call a packing nut that should seal the valve up, but there is no place for an O ring, or any evidence of any packing. There is enough clearance between the valve shaft and the packing nut that as soon as the burner valve is opened gas escapes around the shaft. My first thought is that perhaps some type of packing material is placed in the cavity between the packing nut and the valve control and when tightened fills around the shaft. That is only speculation on my part – so any help would be greatly appreciated on how to seal around the valve shafts to make this stove functional and safe. Thanks very much.
