I found parts for my AH81 on Vintage Karting Association site, a few years back. They used these engines on go karts. I copied the info from the current site.

Think mine needs new rings but I might just source some that are the right size. There used to be a website that had all kinds of parts for these engine mainly as kart engines. Wish I could find a clutch for the Eatons for .404 or 3/8 chain it would be fun to drag out and have some fun with once and a while but I don’t want to wreck the almost new loop of 7/16 chain.
Thanks saving that info for sure
