Re: Float A motor and noise
One tooth off your engine will run but not very well. This can be easily checked by looking at the valves and piston as the piston passes over TDC on the overlap stroke. Remove the side cover and as the piston passes over TDC one valve should be just opening and the other just closing by equal amounts. I have new FAM mounts. I have eliminated the bottom spring on the front mount by replacing it with a rubber shock bushing which fit as though it were made for it. Next I am thinking about the exhaust system.
