[QUOTE="Loggerhead Mike, post: 50523, member: 774"] take your plug out and ground it to the head. is the spark nice'n blue? my motor did a simular thing. it would start and idle, but in gear under load at wot it wouldnt build any rpms. turned out i had a vacuum leak from not replacing the carb gasket after rebuilding the carb. id clean the plug, try and get it to start and run it for awile, so you can look at the plug and see if its runing rich or lean [/QUOTE]
