Anybody out there seen a Saito 56 rip a 10 mm square chunk out of the chrome cylinder? I purchased the engine second hand, with 15hrs on it supposedly, so I really can't comment on its use or storage. When I got it home, I lubed it with after run oil, ran one tank of Coolpower 10% through it and it ran fine. A few weeks later I ran another tank through it, and about 1/2 way through the tank, it stopped, and I thought the fuel was empty. I turned the prop, and no compression. I stripped it down, and saw the mentioned damage. Could this be caused by poor storage methods by the previous owner? I am not sure as to why this happened. The remaining chrome in the cylinder looks fine. Any clues as I don't want this to happen again when I buy a new one.

Thanks.
