This Bugeye flywheel needs a good dentist. At about 8:30, this flywheel lost a tooth.
If you are unfamiliar, the starter motor engages these metal teeth to spin the engine, and should you engage the starter while the engine is running, the starter munches the gears (see photo).
The only way to fix this problem is to pull the engine and flywheel and it’s a lot of work. So don’t do this, be kind to your flywheel, and it will last for generations.
In the photo on the right you can see the new ring gear (left) which will get pressed on to the flywheel to replace the damaged teeth and start the clock all over again!
