I had my old Coleman two burner propane stove for over 40 years and it worked like a charm until it died last year. Naturally, I bought an updated model of the same stove since I had such good experience with the old one. Unfortunately, as with most things we buy nowadays, the new model didn't live up to expectations. The main problem was the inability to throttle the burners down to lower settings. It was like they were either on full or off. I kind of lived with it for a few trips but finally found a fix after reading the feedback on the stove on Amazon. The fix was really quite simple. The problem is apparently caused by the grease that Coleman uses on the throttle valves. First, I removed the knobs by removing the small phillips head screw that holds them on. This takes a good bit of pressure with a small phillips head screwdriver so I had to set the stove on its back end in order to get enough pressure to break the screws loose. I then removed the brass nuts that hold the valves to the casing. Then the valves can be unscrewed and removed. I found the two O-rings on each valve covered in black grease and I removed all the grease with a clean, lint free cloth. I also used a rod from my gun cleaning kit to swab the grease out of the inside area that the valves screw into. I then put a light coating of silicone grease on the O-rings and reinstalled everything. The difference was amazing. I can now throttle both burners from low to high with no problem. Hope this can help someone else who may be having this problem.
