Well I got it running! Rechecked the coil and readings #1 & #3 were the same. Not sure what was causing the no spark condition before I started messing with it (the wire coming from the condenser had damaged insulation and I could see the bare wire, so I suspect that was it) but after swapping in the points from the other saw, I didn't check the gap. Set the gap to 0.015 and away we went. I didn't want to rail on it too hard because the kids are asleep, but it sounds like it runs ok.
I noticed a decent amount of what I presume is bar oil on the bench. Not sure if it leaked out when I had it sitting upright or on its side with the flywheel pointed up. Is this normal?
