Elevation "play" is it normal? I provided a photo. If place my arrow II antenna on the antrunner it tilts about 10 degrees. Worried that is skewing it's ability to track.

Also where can I go in and change the azimuth initial rotation occurring?

grbltrk_rot_get_position: (az, el) = (63.000, 0.000)

I had the same problem. There is a second thread in the axis. I inserted a second set screw there. You should tighten both screws regularly. Since then, the play has significantly improved.

Generally, the screws are loose. Please tighten them with a hexagonal wrench.
