I have a 235 engine, 12volt, but I believe that the tranny was never changed and the flywheel is still the same. Due to the fact that I have changed the starter 3 times. My mechanic states that the flywheel is missing teeth and causes the starter to take a crap. Question 1: Do I have to go out and find a 12 volt flywheel or will buying the flywheel gear ring fit on that 6 volt flywheel. Question 2: If I have to buy the flywheel does anyone know were I can buy one online. Thanks. J :confused:
