More updates on the eternal project... As I mentioned, I went through the entire ignition. I cleaned and sanded (1000 grit) every contact. I set the points at .020, module at .010 and new plug at .020. Nice, bright blue spark. There it sat last night. This morning I test fired the saw with the bare minimum of parts to make it run in the event of failure and the need to tear it back down. She started without incident.
I put all of the ancillary covers in place, save the "hood" (SenDEC tach can't read through the aluminum) and heat cycled a second time without incident.
After taking my son to his first full-on hockey clinic (he's 3 and LOVED it, very proud of him), it was well past sundown. I heat cycled it again (video coming). No further troubles. This old girl and I are still getting acquainted and I'm building her up slowly. Leery of that flywheel loosing itself and I was tuning the carb all along. As I went, she would wind out then fall flat on her face at WOT. She vibes BIGTIME so controlling the screwdriver is a challenge. For the third heat cycle, I brought things to a boil slowly. In this video, when I finally made a power pull, I hit 10,150 rpm. She still comes off slowly when hot, not sure if there's an air leak or throttle float (you can see me manually forcing the butterfly late in the vid). I haven't the means for a pressure test so I'll farm that out to the local shops if necessary.
I know the chain's too tight, but like I said, we're just getting acquainted... There's some more fine-tuning on the carb to handle.
I plan to cut tomorrow, so she'll see wood tomorrow, I hope. More vids to follow.

BTW, weird thing with the SenDEC tach. It shows idle rpm at 4800 to 5500... Obviously it isn't turning that fast. As I built revs slowly, she registered north of 6000, then cut back to mid 3000s and read normally out to 10000+. Not sure if that is a quirk of the points ignition delivering low-rpm multi-spark or what...
