hey so ive got a 2006 yamaha blaster special edition and ive never even got to ride yet bought a engine off a ebay seller with a wiseco piston with 4 hours on it. and for a long time she seem to kick over fine but as of lately it feels really wrong sometimes i go to kick her over and it just stops midway or just feels stuck or jammed but it will still go all the way down.and yes ive been in the side of the crankcase and everything seems fine. also sometimes she will start and when she does she revs up extremely high without me giving her any gas. she used to idle fine and turn on first kick before i bought a carburetor kit because she wouldn't stop leaking gas and now she dosent leak at all. the float is adjusted to stock height. ive been through so much with this f*cking quad and any help would be much appreciated
