I did this saw for someone I met through AS. He bought it on Craigslist not knowing what to look for and got screwed with this basket case. The air filter was some homemade contraption. The gasket had been deleted and the cylinder was sealed with what appeared to be RTV. Piston was scored and sanded down. Some half ass grinding had been done on the exhaust port. Muffler mod, carb full of saw dust.
I machined 0.045 off the cylinder base and set the squish at 0.02 after assembly it was at 210 PSI compression. Polished and opened up the exhaust 65% of the bore. Intake set at 65% as well. Altered the timing slightly. New air filter, sharpened the chain and a carb kit

Numbers were 101, 72, 127
A few things I didn't consider before lowering the jug that much; muffler attaches to the case (easy fix), coil attaches to the cylinder side. I had to elongate the mounting holes to get it low enough.
Questions, comments, concerns welcome. Thanks for looking. Video to follow.
