Motor won't run

The things that Ernie is saying are good, but for later. Don't ever pull the head before you know what the compression is.One exception on his list is running the engine for any period of time with potential trash and metal in the pan. Just changing the oil won't remove trash, pan got to come off. Ok to get to stsrt and that is going to require a suitable tester.
 
If you do indeed have low compression then you should do a leak down test
to see where the problem is.

Yeah, compression gauge needs schrader valve to be accurate, but most important is consistent readings across all cyls. Oil test if there is a difference to determine rings or valves at fault.

Back to coil - I assume you replaced both coil and dist. wire when you converted to 12V, so not likely to be the problem... Disconnect the battery and check the resistance across the ignition switch, should be nearly zero ohms. Could be the contacts are corroded, which would cause a weak spark.

What a beautiful car! When you get it ticking, polish up that rust and go! Around here you'd need a front bumper and horn to be legal, though. Brake light would be a plus.
