Yes, it is a ringed engine. Replacement rings are still available.

The groove in that piston looks far too small for a ring. Looks like a piston from an ABC car engine that have oil grooves cut into them. I certainly could be and probably am wrong but I've never seen a ringed piston with a ring that narrow.

This is no ring in the engine, it is a oil groove into the piston.

Hi........That engine is a early OS "FSR-ABC".................ringless. No ring.

They made both versions..............The FSR version being "ringed" and the FSR-ABC version being ringless.

I currently have that engine (piped) in a Glen Spickler sport 500 & it is a screamer.

Enjoy

I heard it it was a great engine,you have a liner and ringed piston you can sell,does it go right in,thanks!

pardon my rudeness here, but in your other thread you claim to have done "drag engines" for 18 years and you can't tell that this is a simple oil groove?

the groove you see however was when OS had their act together, but certainly can't be mistakin for a ring groove[:-]

just put a gas carb on it like you did that poor ol Como and have fun

Motorboy

Not enough material in piston to make ring groove. Better to buy a liner/piston set for ringed FSR engine or a used engine ringed 45 FSR in good condition to example in EEEBBAAYYY.

Skip, why not just run the engine the way it is now and not worry trying to find a ringed piston? Its a GOOD engine as it sits .
