I changed the generator on my Coleman 413H and thought that would cure the problem as the stove is 20 years old and has worked wonderfully all this time. I then took the burners apart and cleaned the burners and assembled them exactly as I took them apart. My fuel is probably 5 years old.

The burners still do not generate correctly.
