Are you trying to run the motor without the blade plate on?
If so you will continue to shear the flywheel key.
If the boss on the blade plate has movement in it shear as well.
I hope that this will help.

I have found this a common problem with 4 hp B@S motors with the alloy key. I always clean the crankshaft taper and the inside of the flywheel and the key with lacquer thinners to remove any trace of oil, no more problems. You must also make sure the retaining nut is very tight.
cheers,
Wal
