Point gap/dwell settings are an either/or situation. Just set the gap to .020", run the engine, and use a dwell meter to check for the corresponding dwell setting. It's impossible to set the points to one gap, and then make a dwell setting without changing the point gap. "Dwell" is the number of degrees of distributor rotation the points are closed ("Dwell Together" is the literal meaning). Point gap and dwell are inversely proportional- - - -as the gap gets narrower, degrees of dwell increase. It's possible to use an analog voltmeter to set dwell, but that's a subject for a PM exchange or a phone call.
