Ok folks. I just received a New CS 2240. Looking it over, I decided to pull the Champion plug and screw in a NGK. While the plug was out I flashed my light in the cylinder. To my surprise the exhaust port side of the cylinder looked sanded on as it would look if one were to clean up transfer from a scorned piston. So I checked the piston/ring through the exhaust port and it was new. The saw was brand new , I could not see where it had been worked on. As it goes , the saw is now running great and does not show much blow by at all. Ever see this on a new cylinder anybody ?
