If you have to adjust the coil, make sure you adjust slightly the frequency coil end and not the horizontal waveform adjustment on the other end.
Can you still not see the black stripe on the left? If not then we will have to investigate the retrace time.

Terry,
I'm not so sure this TV uses that exact horiz oscillator circuit. Take a look at the schematic below. I don't see the separate horiz frequency control you speak of. All I have are the horiz hold, and the horiz waveform controls. The horiz hold on this set is a coil (L40 on the schematic). RCA called this a deluxe model TV, but it sure seems to be missing a few key circuit adjusting controls.
