2008 RXP X 75 hours won’t start and backfires through the exhaust. I just reinstalled the engine after pulling it to diagnose severe smoking issue. It was exhaust valve seals that were leaking. Took the head to a machine shop for new valves, new seals and the head milled. New head gasket, bolts, front and rear oil pump assembly. I also replaced the starter double gear (ring gear) and Bendix Starter because of wear.
Timing, I used the cam and crankshaft locking bolts, marked the timing chain while 3# piston was at TDC. I even checked it again after backfiring and while harder to figure out TDC with the head on the camshaft sprocket lines appear to line up. Replacing the starter double gear (ring gear) requires removal of the stator, I lined up the location pin on the crankshaft end and ring gear but don’t remember if the trigger wheel had one. I do remember placing the cut out on top. I didn’t find a mark on the stator so I positioned the number stamp on the stator between the trigger wheel cut out. Thoughts on what to check?
