Copy that. Should be an easy check. Thanks for a good way to confirm it.

Gaskets are available for your engine, which crosses to a Robin EY20.
Thanks Rivets.
I have these engine numbers. You probably need more numbers?

Service manual pdf says 6.3:1 compression ratio. Wonder if my 60psi would equate to that? Sounds plausible.
Pdf file says cast iron bore. Thought it was.
Forged high carbon steel crank and forged rod. No wonder these were such sought after engines.

6.3 x 14 = 88.2 PSI so it is a little low

If you open up the valve clearance sufficient to defeat any ACR built into the engine.

Yes, it is iron sleeve.
Sounds like the bottom ring is not wiping the oil off the cyl wall or perhaps the drain holes from that ring are all clogged.
If I were u, i would remove the piston and clean the piston and replace the rings. I mean it is 30ish years old....
While you are at it, rent the cylinder bore gauge from Autozone or the like and measure it while it is open to see if the cyl is out of round.
Gasket wise, i used silicone gasket when i opened mine up, and you can always make a gasket for the cylinder head if yours falls apart.
