Last spring, fellow AS member bigbadbob was kind enough to outright give me the diamond in the rough IN THIS THREAD, where jokes were made about sending it to the dumpster! Well, I finally got around to cleaning it up and getting it going over the holidays this winter. It was a bit of an experience. That saw has some things I've never seen the likes of before.
All the parts have been washed with Varsol and sat out overnight to dry out.
Ever seen a clutch like that one before? I didn't fiddle with it at all, so I don't know if that's just a snap-on cover overtop of a clutch of standard design, or if it's some funky proprietary clutch design or something. You'll also notice that it's missing a bit more paint than before. That's a result of the 120 PSI air nozzle that I used to hog off most of the stuff that was stuck to the saw before washing it. I only stripped it down to the parts laid out here, I didn't bother taking it right down to check all the bearings and everything.
Another unique thing about the saw. I've never seen a cylinder like that one before. It has a removable head, like a lawnmower engine, and there's a flange on the head that fits down inside the cylinder. The piston has a chamfered top edge, which comes up and fits into the flange on the head very snugly. The compression chamber is a very steep "cone" recess from there up to the spark plug, which is threaded in 90° to the cylinder. This makes me think this saw could benefit from a better plug with multiple electrodes.
This is the exhaust port. The cylinder and piston are still in excellent shape.Both ports are covered by the cylinder liner and have three holes drilled through as seen here. I've never seen something like this before either. I wonder if there would be a decent performance boost if one were to open the ports up completely?
All put back together! Time to get it going. To get it going quicker in case the carb was a bit sluggish, I squirted a bit of gas straight into the intake. That didn't take long to get it going. KEEPING it going, on the other hand, was a bit trickier.
