Would anyone know where I could get the internal parts to rebuild an ASP 91ABC engine?

He was the Magnum distributer as far as I know and might still have some old stock. Magnum is rebadged ASP, and identical in every practical way.

But it could prove cheaper to just go look for a used good ASP/Magnum .91 if you can find one.

I believe that ASP engines and Magnum engines were the same internally. https://www.mikegoesflying.com/ is the Website that has parts for Magnums. He has a sleeve and piston for Magnums there

I have several different types side by side of each, and can confirm they are identical engines with minor cosmetic changes and a different badge.
At least, the later versions. The earlier versions (pre-2000), not 100% sure, I do not have "couples" of those.
