[QUOTE="Pappy, post: 304514, member: 3278"] If you have done all of this and it is still lean spitting at idle you may have either an upper seal or a lower seal on the crankshaft that has or is in the process of failing. Do you see alot of black oily residue coming from under the flywheel area? Rebuilding the carb would be the first place to go so you are hopefully on the right track. Make sure you pull the core plug on the top of the carb when you clean it. Under that core plug are the tiny calibration holes that make that engine idle. Always possible one is plugged or partially plugged and not allowing you to get a nood needle set on the engine. Carefully drill the core plug with a 1/8" drill bit. Do not allow that bit to go screaming down and hit the bottom of the carb when it goes through the plug. Pry out the plug once you have made the hole. [/QUOTE]
