Max,
I have never taken my distributor out to change the points, maybe I'm
shorter than you. I use a dwell meter and adjust while cranking. Then put
the cap on and check while running. I usually have to readjust a bit as the
cranking dwell and running dwell are a couple of degrees off and I forget
from one set of points to another how much to compensate for. I just
purchased a Pertronix for my 72 B but haven't put it in yet. Too many kids
cars to fix first. I usually know to change points when my B doesn't start
within a couple of seconds of cranking. I don't mind setting the points,
but thought the electronic ignition might make the old ragtop run a bit
better.
Dave 72 B
