Default Re: Model b motor

The sound is very likely caused by loose flywheel bolts, not uncommon on 4 cylinder engines. The crank touching the dipper tray would not make a knocking sound may be the wrong tray? A's came with 2 or 3 different trays over the years, the B tray should have 4 large, maybe ", holes in the top, flat surface, not sure all B's had those?
