If you have the Sams for it, do the chroma bandpass alignment. Sounds like one demodulator is being driven more than the other, that would not be a phasing coil issue but rather an issue with the transformer coupling the local oscillator to the demods. One is probably peaked higher than the other. If it's anything like other chassis, the proceedure will go something like this:
using the VTVM on the CW driver trans, peak for maximum output
Or something to that effect. Once the local osc has equal output to the demods, you should zero beat the osc and make sure the phase detector is doing it's job.
