i got a 2005 polaris 330 trailboss that i thought was running real rich. i pulled the carb and everything is in excellent shape. but the plugs are very black so i got out the timing light and sure enough the timing is so retarded that its firing about a quarter inch to the right of the TDC mark. it should be firing about 1 1/4 inch to the right of the tdc mark. has anyone else seen this problem and been able to solve it? ive read some on here and it seems to be an ongoing issue with polaris quads. has anyone ever changed the pickup and it fixed the problem? thanks for any help

 

Pull the flywheel,the stator plate is adjustable. Loosen the five (5) stator plate screws slightly,turn plate left to advance timing. Check where mark is on stator plate and case mark before you move for reference. Reassemble and then check timing. OPT
