Hi guys, sorry about the dumb question, but this is an OEM piston, correct?
The only marking I could find is "ART" in the inside:
I got this together with the matching cylinder as a spare and I want to use it. Ring gap measures .028", so I need to order new rings. The rest looks really good, except:
Looks like it ate a reed? No sign of damage on the cylinder wall, will this be safe to use? It appears it ran this way.
Thanks!
