high starting compression sheared flywheel key MS250

The ‘cast in key’ deal sucks, really.

I been spreading a thin layer of corse valve lapping compound (water base) on the taper.

A little tip.On anything thing that uses a taper fit acetone makes a good cleaner on both the bore and the shaft .Another option is to heat the bore up with a heat gun before you screw it down .
