Added an SP70 to my collection this past week. I think I probably paid a little too much for it off of eBay.... but cosmetically it is pretty clean on the outside and has strong blue spark and runs fine (once I got it tuned) plus the auto/manual oiler works. Whoever had it previous had the idle set reallllll low and had it running richer than Bill Gates. There is some very light scoring on the cylinder toward the exhaust side. I believe that is causing the 155 PSI compression reading. That's probably still good for that saw but I have a PM60 at 163 PSI and a Freshly rebuilt 600002U 10-10A at close to 160 PSI with fresh rings/piston. Anyways here's some pics/video of the old girl.
