This sounds purely like a fuel issue.... more specifically... a flooding issue... does the engine start good cold ?.... most likely a good carb cleaning is in order... Today's fuel has specific problems associated with it... when was the last time you changed the fuel filter? do you have a water separating fuel filter... you should.... clean the carb and check the float level... the addition of a new needle and seat would also be a good idea... Star tron is the best fuel additive out there... run it year round to help avoid fuel related problems.
