750 sxi pro has an odd misfire and backfires throughout rev range. pulled stator cover, noticed stator was rusty, replaced stator and new spark plugs. still missing, replaced my whole msd cdi and coil with a known good running bone stock setup, still bad. checked reeds and compression. odd part is when your crank the ski over it "hangs" on the starter motor when it tries to fire like the timing is super advanced. timing mark appears to line up at tdc but will pull flywheel tomorrow to check for sheared key. curious if anyone has ever come across this, starting to scratch my head.
