Disassemble
Turn burner knob out far enough to to gain access to the nut behind to knob (yeah i know, haha).
Then unscrew the knob until it comes out of the assembly.
Next flip the stove and unscrew the burner and remove
At this point I removed the brass restrictor (piece that goes between the knob and burner pipe). I sprayed a cleaner in the direction of gas flow and found it was not spraying out of the restrictor well.This indicated that there was debris in the restrictor.I then cleaned with an spray solvent in the opposite direction of the gas flow. I then rechecked the spray in the correct direction and found it was now flowing properly. I let the brake cleaner dry and reassembled. Once assembled i ran a small amount of propane through the system to ensure no brake cleaner was left and waiting to go bang.
All said this was a repair well worth the time invested. The stove was repaired in very little time and saved us from purchasing a new stove. Old stoves have much more camping cred and Coleman doesn't make green stoves anymore. There now shinny black and look more like a yuppie kitchen appliance than a manly camp stove.I hope someone someday finds this and attempts repair on there old stove, to all of the others that could care less about stove repair sorry maybe next time there will be a hospital story to go with it.
