No Spark?

You can trigger the MSD with the points wire to test it

And you don't even have to go quite that far. On the points input to the MSD, it only requires a make and break trigger. So what I have done in the past is to lay a coarse file on a ground somewhere convenient and then just drag that MSD input wire along the file. With the coilwire near-grounded, a stream of sparks should issue forth. This prooves the MSD and coil are fine.
BTW, in my experience; the CDI ignition systems work best with CDI-compatible coils; like E-cores. The MSD Capacitor discharges at 525 volts IIRC, and 12 volt coils may not endure that for long.
