Jeff I have a heap of those starters, never had the heart to throw them out and never tried one to see if they work. I just make up a blanking plate to cover the exposed tooth section where the motor bolts on. 2 screws hold the motor on. Battery is charged by external charger, not by the motor. At least they kept the pull starter, not like some of the new models that are electric start only, really dumb idea. A good pull starter is always a good win, plus carby,coil module and other goodies. Never know what you will need in the future, some bits might get hard to obtain one day.
