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?

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.
