I don't know that this method is approved, but seemed to do the trick for me. Take your little 2.5lb propane torch commenly used for soldering or heating something small. Stick the end of the torch (NOT LIT) into the carb open valve 3 - 5 seconds, remove, try starting engine. Better then spilling gas all over. Like I said, I don't know if this method is approved, as with any experimental drug, always keep a fire extinguisher handy. As I mentioned it was 5 -6 yrs ago that I rebuilt my engine, which I bought from a guy that told me it hadn't run in about 15 yrs. When it started, I was in shock, what a good feeling!! I was even happier to find that I had a beer in the refrigerator! Good Luck, Keith
