Default Re: How in heck does this thing work? (Nu rex)

To get the timing absolutely perfect, the only way to do that is a perfect TDC in #1 cyl, and a timing light that will determine the very instant when the points open.

To find perfect TDC, the timing pin will serve as a reference point, but removing the spark plug in #1 cyl, and rotating the crankshaft while observing the piston through the spark plug hole, is the only real way to find a perfect TDC.

Is there a more perfect way to do it?....and, is it relevant to a good running model A engine?

Seems to me there is a little wiggle room for getting a good running engine, specifically because the spark advance is manual, and not centrifugal, vacuum, or some other form of automatic adjustment.
