Lets back this train up to the station…TIMING is a concept that confuses the issue here

You set the each set of points at top of cam. You rotate flywheel to line up opening in flywheel with each set at the high point of cam.

That does it

When you move the magneto handle you advance or retard ignition in relation event
thus varing timing..
You will note the front of motor has a Stop, Slow, Start and Fast positions marked
As you move lever from Stop to Fast you are advancing timing as well as opening carburetor shutter.

When you are setting points at high point of cam the position of magneto lever
is irrelevant. It is all about setting the gap against the high point of the cam. If the
point gaps are right for both sets of points you are good to go. as far as ignition
is concerned.
