That Mag MIGHT work once with the tooth missing but I would chance it!
Is this an early J style or later U style? Makes a slight difference in Pony removal.
This magneto look like a WICO and with missing teeth on the gear you should check the flywell she must be shaking and by a bad front crankshaft bearing and check if the flywell is going up and dan and yes you better pulling the starting engine before more trouble.
You may be able to snag the broken-off tooth out of the gear chamber with a magnet, but if you can't, you'll need to pull the pinion assembly so you can fish it out. Don't be tempted to leave it in there
Hi Team,
shaft breakage was an initial problem and when that was addressed then tooth breakage become the result with loose flywheel--as Hector said-- and/or excessively worn pony main bearings, also excessive crankshaft end float could be an influence as well.
Cheers,
Eddie B.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
