Flywheel properly seated ??
I put my cam , and 4 degree advance key in today, and the key was a tight fit in the groove on the crank . I tapped it into place with a screwdriver handle, and installed the flywheel. I came in and ate, and checked my phone. Just by coincidence a guy on the Facebook page had just installed a key, and it sheared. Someone replied that the flywheel may not have been tight enough. I went back out, and ready tighten mine up good, but I also noticed that the starter sprag can still slide back and forth a little on the crank. Is it supposed to be able to do this?

Yes the bolt is tight. My cordless impact gun would not remove it yesterday, so I took a pair of tin snips with rubber grips, and squeezed the grips together so they would slip under the piston, and across the opening in the block, and used a long breaker bar on it, and my piston tilted and cracked the skirt, but the bolt did come out. I took the piston off and stuck the wrist pin in the rod, and stuck a long 1/4" extension though the wrist pin, to bridge the opening in the block. I used thick rubber tubing on top of the block to keep from damaging the gasket surface, and I tightened the flywheel really tight with the same long breaker bar. I was just a little worried that maybe the key might have got pushed back to far in the groove, and maybe one end of it was high. I don't even know if that's possible though. The bottom of the key is rounded, so I hope it kinda finds it's proper place to seat.

Gee
I think I will stick with variable electronic advance ! I know the bearings get smacked with combustion but there must be a way to use the rotor itself to hold it. I have strap wrenches. One might be big enough for the rotor. The thought of subjecting the bearings to that stress is enough to convince me.

I have a pneumatic impact wrench that would loosen that bolt quickly. I could probably just stabilize the rotor with my left hand while doing it. That would minimize bearing/piston/case stress.
Same goes for installing, but I would probably use a strap wrench. I wonder if just some locktite (blue) and moderate torque is sufficient. It is just held in place. The woodruff key does the work.
