1. The B terminal on the plug measures 12 V with the ignition on. However, when I connect the B terminal on the plug with the B pin on the CDI via an alligator clip, the voltage on the B pin goes to <1 V and the C pin reads < 1 V. If I connect the B pin on the CDI directly to the battery the C pin reads 12 V. I think this is where the problem may lie. When the CDI unit is plugged into its connector, the voltage drops to <1.

That's the source of your problem. That power source normally comes from your ignition switch.

That's good.

Actually, that measurement should be between the B pin and the C pin with the CDI disconnected.

So it looks like you've had an intermittent/poor power source to your CDI pin B.
Before troubleshooting the power problem, use a jumper wire to power the B pin by
connecting the wire to one of the fuses on the left side near the big engine harness
connector. Hopefully, your engine should start.
