Thank you for your responses. Here is what I did after work:

Test fire, would barely start, and only with the pedal applied to keep it running, will not idle by itself.

Installed six new J12YC plugs. The six I removed were heavily covered in soot, especially for only running 40-50 miles and for three hours. It's running rich, I see that.

Test fire, smoother, but still not holding idle, and still not running right.

Go to carb, return idle advance to just making contact, then 1 1/4 turns in. Then turn idle mixture all the way in, and back out two turns.

Test fire, no change.

Check distributor. Vac advance screw is slightly loose, and octane selector not at 0. New hardware for the screw to tighten, set octane selector to zero.

Test fire, no change.

Back out mixture screw 1/2, test fire, 1/2 again, test fire. No change.

Disconnected vacuum advance and sucked on it, I was able to turn the dizzy slightly.

If anyone sees a "hey dummy" in the picture below I'd be happy to feel stupid for a while if it meant it got fixed.

Again, thanks for all the help.
