Moderator Cynic Posted January 20, 2013 Moderator Share Posted January 20, 2013 Starting the same thread again wont help. I agree with airhead check your spark.

Moderator drewpy Posted January 20, 2013 Moderator Share Posted January 20, 2013 or the float needle is dirty letting too much fuel into the carb. a quick check and clean is all it may need. Link to comment Share on other sites More sharing options...
