2. Move the distributor shaft one tooth CCW and retest.
I will keep you all posted.

If you have moved the rotor (& dist. shaft) one tooth CCW, you have further retarded the firing point. Recall that in your first post you described rotating the distributor
BODY CCW, and finding that the engine ran better. Rotating the dist. body CCW advances the firing point, and repositioning (rotating) the
ROTOR CW also advances the firing point.
If you have moved the rotor one tooth CCW, you will now need to go back CW one tooth to return to your starting point, and then one more tooth CW to advance the firing point.
This problem seems to be caused by the Pertronix pickup and magnets falling in a slightly different orientation with respect to the dist. shaft than the original points and breaker cam.
