Hi- does anyone know whether one can replace the drive cup on a Honda mower? I messed up the pull cord starter and it chewed up the drive cup on top of the engine, which seems like an integral part of the mower. We are replacing the starter thing with the cord, but how about the cup on top that connects the starter assembly to the motor? Any suggestions would be most welcome. Was looking forward to mulching the leaves but may have to rake them the old fashioned way-
