    Jim,
    Just looked up some bearings on the crankshaft. Almost everything has roller bearings except the wrist pin uses bushings except the 30 & 33 hp motors in the Scott Version. I need more data for the Firestone motor but bet they are the same. I am looking forward to restore the cast aluminum shroud motor. Can you shed any light on what year the aluminum cast shrouds were used
    Thank yoy,
    Jeff
