I have a Classic 375 Briggs which starts and runs well, no smoke. The starter failed on it the other day. This is the starter on the top of the engine but is actually part of the housing, not separate like they usually are. Underneath its all metal with the ball bearings as the engagement mechanism. Do any of the cheap starters fit after you cut off the existing one?. I just happen to have a few good starters for the earlier model, the side starter direct upward pull but they wont fit as there is no gear on the flywheel. Maybe change the flywheel too?
Can not spend very much on a Briggs these days and I do not hold them very high in my opinion. Probably have to wait until I see another engine which is worn out. Should be plenty around.
All the best
