pre engaged starter motors for a '65 850.

I seem to have two motors with different numbers of teeth, one 9 and one 10 tooth.

Which is correct or are they interchangeable ?

Pre-engaged starter motors with the integral solonoid were only fitted to Minis from 1985 onwards:-

Ouote below from Old Skool Minis may help:-
"Inertia starter motor with the correct 9 tooth pinion for all Minis up to the fitment of the pre engaged type in approx 1984/1985. DO NOT fit the 10 tooth starter motor sold by many as it can ruin the ring gear or the bendix. Other Leyland cars used the 10 tooth such as Sprite, Spitfire etc and often get fitted as they are cheaper but 9 teeth is rarer to buy but is meant for Mini 107 teeth ring gears."

It would have originally been a 9 tooth Inertia Starter. 107 tooth ring gear in the flywheel.

9 tooth inertia starter is correct for your car. The 10 tooth was mainly fitted to early Metro engines and I believe inline engines.
