Is this the later style breaker plate assembly you are describing?

I see a pin and slot that seems to not allow the plates to move out of egocentricity ... ... (Where did I come across that word?)



You are correct and I am wrong Sir. The rule is that dwell variation with increased RPM should not vary more than three degrees if not the AUTOLITE two piece breaker plate assy, the upper plate swinging in an arc causes resultant dwell variation that can be up to twelve degrees variation with that design.

I found an old tech sheet and will post it when my scanner returns to Earth orbit.

I am truly sorry if I caused any confusion...

EDIT -

While I am sucking up dust, the second adj hole in the points set is for adjusting points breaker arm spring tension, not dwell angle.

I expect oldmics to call me on the carpet and tear off a few patches...
