QUESTION - I have a flywheel 1203/1204 with a single keyway, when I line up the magnets with a dual keyway 1203 flywheel the single keyway lines up with the 1:00 keyway rather than the 12:00 keyway when viewed from the outboard side. So is this a limited or unlimited flywheel??
Thanks
Dave

I don't see any X or P markings on the 1203 dual keyway model, I am wondering if the right or left keyway is the X?
the flywheel on the left here is a dual marked 1203/1204 and the one on the right is the 1203 dual keyway, I cleaned it as best I can without going ultrasonic and don't find an X or P anywhere.

Front of single keyway 1203/1204 flywheel the slot lines up with the right slot on the dual key above.
Pics are PB so held hostage.
