I thought I posted the solution to the list, but it may not have
made it. I have added the original note below in case it did not get
routed somehow. Dave More up north was the winner.

DING, DING DING!!!!!
We have a winner!!! Attaboy Dave, your kung fu is the best.
Points gap (or alternately - "dwell") was off by a country mile. Bentley
says 35 +/- 3 degrees of dwell, my points were set to 60 degrees of
dwell. Dwell can be approximated by setting the open gap of the points
to a known value (the actual spec eludes me at the moment). This is less
accurate than a dwell meter however as the dizzy can wear, etc, but it
gets the dwell acceptably close. I purchased an actual meter to set the
Perhaps someone could explain to me why this only matters at low RPM. I
know that dwell affects two things; Amount of energy stored in the coil
to fire the plug, and the amount of time permitted for the plug to fire.
But it seems to me that this should be a problem at high RPM, not low
RPM. At high RPM the amount of time for the coil to "charge" is much
shorter and therefore it seems as though this should be when you develop
Anyway, Dave gets the attaboy...
