Sounds like it might be running too rich. An adjustment on the fuel/air mixture on the carb may help. Also check your float bowl levels to make sure they are not too high. The only other thing I can think of is that the choke may be sticking. Good luck.

yes, and "IF" that's the problem that may fix it. but there could be other issues. float level, etc. is the choke ALL THE WAY OPEN when the engine is warmed up? a stuck choke could cause it to run rich too.
