I replaced a few in the Horiz Osc circuit and now it'll fall into range with the control, though it'll only flop one direction, I wish it had a fine Horiz adjustment.
I finally hooked up a speaker and found out I had no sound at all, a little poking around turned up a resistor I had broken while recapping, replacing that got me some static, tweaking the fine tuning and the coils in the sound circuit got it working well but only with the picture tuned off peak a little bit so it needs more work there.

Please note...
These sets did NOT have AFC for the horizontal oscillator. It is a straight blocking oscillator circuit. As a result, the horizontal hold control will be VERY critical in adjustment.
This is normal.
