I just picked up a single and a double burner picnic stove. The single burner still had a can attached that was about half full, it still lit but I didn't think that the flame was decent. I can see why the cans were discontinued, does not take too much to make them leak just under the burner where the can seals. I am goin to take off the can fitting and machine one out of brass re-soldier the small tube back on and make it so I can use a separate hose and an adjustable regulator to see if I can get the air/fuel ratio right and maybe it will work, that is the plan anyway. I think these little stoves are cool and very retro looking but I want it to be safe.
