Hello all. After reading couple of threads I think I made a huge mistake. I have a classic 50 45hp about 1985 and it didnt have electric start and a flywheel with a ring gear. So I bought them this winter and installed them. I didnt have flywheel puller and also had only the outer piece of flywheel with a ring gear. So I unscrewd the 8 small bolts, took the flywheel outer part off and put new piece in and put the small bolts back. Didnt make any marks of a correct position etc. Did I make a huge mistake... thanks.
