Successful update!
She starts!. and my problem was not necessarily that the points advancer was out, but that I had it installed in its bracket incorrectly to begin with. After examining both pieces closely, I realized I had not seated the cylinder properly by nesting it into the bracket properly. Once amended, it started on the second kick.
I took it around the block and it was rather gutless. So I took the carbs apart to find that one of the vacuum pins had come disconnected. I fixed that up too and now she is more spry than I've ever experienced.
Thank all of you for your input and forbearance with me as I've struggled through my first rebuild.
