This is the engine from that link. I’ll have to turn it over and see if the bad teeth on the ring gear coincides with the compression stroke. The rest of the engine is in beautiful shape.jMike, Is that the engine I sent you the craigslist link for in central Ohio? It did not look like it had an outboard ring gear from the pictures in the listing.
I have seen engines with starters connected by belt to pulley's and magneto ignitions, but not many. I don't recall seeing an engine with a starter-generator that had a magneto ignition.From what I've seen, if the engine was factory equipped with the starter and gen that they also used a distributor and coil instead of the mag.
