It looks more like a frequency problem rather than a sync problem at this point, the oscillator is probably running too slow.
Did you adjust the Horiz Freq coil? I believe it's on the back apron on the 630 but some RCA's have it underneath the chassis on the inside.
This is an adjustable slug rather than a Potentiometer.
Do you have the Sam's on it? If you do try running the Horizontal alignment procedure.
Next guess would be that you did install a wrong value part somewhere, possibly a .001 where a .01 is called for, double check your work around the Horiz Osc tube and Sync Separator tube, also around that frequency coil.
Also a resistor in the Horiz circuit that has drifted way up in value can cause this.
Sometimes I'll just jump another .01 cap across the caps in the horizontal section till I find one that changes it drastically, that can help narrow it down quickly.
