Vince Falter at his most excellent site Fordgarage.com has some useful timing description at
https://www.fordgarage.com/pages/timingiseverything.htm
One observation of note: the Model A is entirely too "adjustable" in timing. Proper timing position for anything but extreme high speed is about half way down the the sector. The Model B timing is "automatic" but only has built in about the same 60 percent range of the Model A total span.
Plus the Model B compression being a bit higher the "sweet spot" is different.
Nkaminar's "Do this" above (post 5) is a way to "check" the sweet spot. That "bricppt" (points arc sound) when you're there is MOST satisfying to hear.
