Well gentlemen, my puzzle is finally solved...
First things first, this is a PSC motor, not split phase, as there is no CF switch.
Here is my final diagram (that works,) both directions and correct torque.
After getting it running correctly, I took it over to the motor shop because I was (and am) confused about the commonality of the black & white leads,
and it doesn't matter if either or both are connected to the cap.
Without testing and just a visual look, he was uncertain as well and explained that usually they go to the source power, so it's still a question.
Additionally, I was quite surprised to see how much torque is applied when the 4MFD cap is installed. Without it in the below config, it spun fast but
could still be stopped with quite a bit of pressure on the shaft.
Anyhow, here's how it's configured to run in both directions. I was able to apply a 3PTT switch for reversing successfully also.
Thanks for all your help and sorry about any confusion from prior posts.
