I'm rebuilding the engine on my FSM after spinning a rod bearing. I replaced the crankshaft, rod, and all of the bearings. Lined up all the
timing marks and secured the timing gears before I installed the timing cover. When I attempted to line up the flywheel 23 degrees before top
dead center and the timing mark on the injector pump it wasn't even close. Probably 90 degrees off and way passed any possible adjustment. I
will say when the tractor was running I attempted to time the injector pump and had the same problem. Also when it was running I needed to go
to almost full throttle in order for it to run. I never could get it to idle down. I checked the injector coupling on the engine end and the
key is intact. I haven't taken the nut off of the coupling on the injector pump yet but wonder if that may be the problem, or do I need to
remove the timing cover again and recheck the gears.
