I missed or deleted the orig post so this may be off base:
If the bearings in the distributor are worn, this can cause
the ignition timing to change under certain conditions. This
really shows if you are still using mechanical breaker points.
The test is to grab the top of the rotor and wiggle from side
to side. If moves at all, the bearings are worn.
