This saw was a pleasure to work on, and is in nice shape.
I pulled the muffler and at first glance the piston appeared to be significantly scored by carbon, but I took a pointy piece of plastic and rubbed it along the bottom of the piston and it was smooth. Then rubbed the ring area of the piston, and had a few scratches, but was mostly smooth. Appears to be mostly blemishing rather than scratches. Compression felt good also.
Anyway, I squirted some pre-mix into the carb, and it fired right up and ran strong. Felt like good compression. I see no need to replace the piston.
Everything looks intact and in good shape on the saw. Chain brake works good. Really interesting saw. Cushion on the top handle is torn a bit on the bottom portion. One of the bar stud nuts is missing. Accepting offers.
