Correct, it is the number of degrees of dizzy rotation for which the ignition contact points stay closed. And dwell degrees are increased or decreased by changing points gap.
And, yes, I see your point. A bit of wear in the top end of the dizzy will change the gap/dwell due to a wobble in the upper portion of the shaft. So rotating a very worn dizzy could change gap/dwell.
Makes perfect sense and I'm tracking with you now. Thanks..
