I fast forwarded this saw. It was tossed for what the owner thought was a damaged flywheel and no compression. Turns out the poly starter ring was worn and only one screw left holding the recoil. Pulled the muffler to check and piston is perfect. Replace the ring, new fuel lines/pulse line, ultra sonic cleaned the carb. Runs real strong, 160psi cold. Will make a good saw for whoever it’s new owner will be
