If there is damage from a 9 tooth starter being used on a ring gear designed for an 8 tooth starter the damage will progress as the flywheel spins. It will appear at one edge of the notch in some places, the middle and then the other edge. Now I've never seen this but it makes mathematical sense. I've never seen a ring gear that didn't work. A few stories about this but nobody has ever taken a picture.

Any chance of that photo without the cobwebs, I can use a file to put back the facets on the lead edge of the tooth.
