My 25 yr old 272 has been ultra-reliable reliable, right down to the original spark plug. Wait, that's a lie: The kill switch broke when it got crushed one time. Anyway, after all these years I did a tear-down inspection. Everything looks fine, just normal wear. I failed to do a comp test so I have no hard numbers on that. That was silly, I know. But, my gut feeling is compression good.
While I've got it apart I feel like I should do something' - like re-ring it. So, here's my questions:
Is it ok to install a new piston ring, or, should the ring and cylinder be a matched set? IOW, could a new ring possibly damage a used cylinder?
Are factory OEM rings available? If so, from who?
Thanks people!
