I do timing on points systems a little different.

I qualify each timing mark on the scale for each cylinder with a dial gauge.

I next set the point gap for ONE set of points.

With a dwell meter, and REGULAR timing light, (if it has a "Dial Back", leave it OFF)

I then start the engine and record that set of points dwell setting, and then, set the timing with the light.
Keep in mind that dwell can change as you set the timing, so you might have to go back and forth,
Read timing, see if dwell changed. The objective is to get the dwell back to its setting, with the timing set correctly.

I then do the same with the other two sets of points, set dwell, read and set timing, bo back and forth on both until correct.

Now, points wear, and, if you dwell set the points, when it comes back to reset, all you need to do is reset the dwell,
and the timing will be right back to correct.

Also, critical, NEVER, EVER sand, file, dress point faces, they are tungsten coated, to help retard burning,
dressing the faces removes the tungsten, causing faster face burning and carbon contamination.

The process of finding the points dwell, setting one set of points with feeler gauge, then finding the dwell

I call that process "Create A Spec", make your own spec, easier than trying to get specs from everywhere in the universe.

Other than point gap, how to adjust dwell?

Maximum dwell is determined by cam ramp lift, up to 100%.

So we need dwell. This is set by point gap.

Timing is completely different.

Dwell is set by points gap. If there is no spec for dwell, use my "Create A Spec" method.

Set ONE set of points to "read", and set the points gap for that one points set.

Dwell meter, select a number of cylinders to use, that part does not hurt readings. Connect to the points.

Start engine, read dwell, that is your dwell spec.

When the iggy ramp is not as new, dwell will decrease, timing will retard.
When points leverage is not correct(aftermarket) all bets are off.
