I was given a small twin cylinder gaso engine...no idea of the manufacturer...looks to be about a 40cc, but haven't measured it. In inspecting the engine, which appears to have never been run, I see that it has 2 piston rings per cylinder...the lower ring of 1 cylinder is broken. Assuming (yes, I know) everything else is OK mechanically, what would be the impact on performance by removing the broken ring from that cylinder and removing the good one from the other...It seems to me that the single ring configuration is more common in small engines that double rings...thoughts?
Thanks
