We'll see. I took it apart and wound it by hand to observe the movement. It would run for a few seconds to maybe 30 seconds then hang up and stop. It wouldn't make it to the points, which don't look fried. I figured it froze up mechanically long ago before the self wind solenoid had a chance to die the usual death.
I noticed if I pushed the second hand in, it would click and resume running. I also noticed it would run almost until the points touched, but stop just short. I thought it was the gear on the second hand shaft and spent a ton of time f-ing with it. I finally realized it was the little tiny pins that catch the saw blade looking gear with the wheel that springs back and forth.
After some close observation I noticed the pins would catch the leading edge of the saw blade. Some very slight leaning of the pins, with lots of trial and error got it working without hanging up.
So, the part about it not making it all the way to the points contacting was resolved by stretching the spring over a few rings and reattaching it.
I got the mechanical part running perfect, but sometimes the points would wind it back up, sometimes they wouldn't. I let them shut on some fine sandpaper folded to hit both contacts. A few good swipes, and a little bending of the tab made the contacts hit nice and square.
Still wouldn't "pop" every time. The car has sat for a long time and a voltage check showed 11 something volts. I threw a charger on at 2 amps and showed 12.75 instantly. Put the clock back on the battery with some jumpers and ZZZZZip, it fired right back up.
Is it going to run all night? A day? A week? We'll see, but a fun bit of research for no cost but time. If it proves too unreliable, I'll just swap in some modern guts but figured this might help others.
