ok, so, after i get it warmed up, and start really getting on the throttle and running it hard, when i just go from low revs and gun it really really fast, it like hesitates...ill try to make an impression...B (hesitates) BRRAAAAAAAP.. and when i turn out the fuel screw it makes it alot better. and ive heard like when finding the correct pilot size, if you turn the fuel screw out all the way and it still idles fine, you need a bigger pilot. correct me if thats wrong. But i may be selling/trading this fourwheeler and the kid wants the jetting to be on, so, i really apreciate everyones help
