Here is a related incident for the list:
After performing a full tune-up on my 1975B (with
Allison point replacement already in the distributor)
experienced intermittent missing at all RPMS and loads.
Seemed random but more prevalent on hot, humid days
after engine warmed up. Idle was perfect. Popping noise
in the radio accompanied the miss. After 2 weeks of use
and checking the smallest possibilities I found that the
spark track on the new cap was at the extreme bottom of
the electrodes. Raised the rotor with a washer and the
miss disapppeared for good :)
Just a little tidbit to add to everyone's archives.
And beware of B@ck-Arnl@y caps and rotors....
