Have you OHM tested your stator and ignition coil yet? And deff check your pilot jet. Pilot jet has a lot to do with your idle.I have a 98 blaster that doesn't want to idle and also likes to hang up after given any throttle.
new cylinder, piston, reeds, carb is clean, and float height correct. passed leakdown test and everything. this thing is really bugging me at this point since it is my wifes quad and want her to be able to ride.
any help is appreciated
