I really doubt that the spinner is causing the engine to stall. I would start over with the break in procedure in the manual. The ABC engines have to be properly broken in and It seems to me that I heard that running way to rich complicated things as it wouldn't let the engine get up to temp quick enough and would cause siezing. Read the manual closely and give it another chance. The starter slipping on the spinner could be that the engine is siezing up from the short run, IE the piston is warming up, but the sleive isn't yet and things get overly tight.

A question, if the engine is cold, IE hasn't rund for at least 15 minutes, does it spin over OK? If it does, that would be an indication that you may be running to rich and the liner isn't getting hot quick enough.
