First of all - my dad has been working on it, and memory is going, so I'm not going to grill him. The flywheel is gone. Then, I'm not sure about the correction. I realize both are 6volt - but I thought the flywheel and starter had to match, am I wrong? Can someone say what I should get? Is the 216 and 235 the same (is that what you were saying)? Help?
