I have a theory on what may have caused my distributor to no longer distribute sparks: the fiber shim, which is over 1 mm thick, was completely disintegrated. This caused the shaft to drop about 1 mm, maybe causing the graphite electrode in the cap to no longer make contact with the rotor. I just got the shims, so once I reassemble the distributor, I will know if my theory was correct.

Also, I measured the 750 ohm to the dizzy coil through the green wire plugged into it, so that eliminated those two components as source of the failure.
