Nope, still sounds terrible, actually worse, and doesn't start without playing around with it every time. Line-to-line means measure the voltage between the two hot wires?

You have dead spot in the windings. As long as it starts away from the dead zone it'll work but that motor sounds like it's toast if you have a healthy circuit breaker and all else checks out.

I replaced my whisperflo motor a few months ago with a Century V-Green motor. If you are confident with the repair you made to the seal plate that would be an option.
