This is the first time i've ever actually removed the governor. We've always just held it back with a spring. If i run it up slow it's good but, if i crack the throttle it hesitates & will die if i don't feather it. I have the aftermarket air filter(off for free flow) so it's getting plenty of air. When i put my strait pipe on it's slightly better. Now it's just more of a haze than spit. Still same symptoms. Advanced thank yous and i'll see you guys at the races.
