Setting Azimuth

Details:
VPI Scoutmaster
JMW 9 standard tonearm
Soundsmith Zephyr cartridge band new
Using a Fozgometer and Hi Fi News Test LP both also brand new
I'm measuring at the interconnects off the turntable.
I cannot seem to achieve a proper azimuth that will give even channel balance. The only adjustment on this tonearm is the counterweight which is weighted a the bottom so turning it side to side should effect azimuth. Only extreme changes are affecting channel balance. I changed the interconnects in case they were causing the problem, but I get the same results. The right channel is a few decibels louder no matter what I do to the azimuth unless I make an extreme adjustment which has the tonearm cocked to one side and obviously this is not correct.

I have a Zephyr and a Counter Intuitive on my JMW 10.5i arm and had little difficulty setting azimuth with my Fozgometer. Peter Ledermann does have reservations (which I've forgotten) about the Fozgometer, by the way.

I love this cart/arm combo but did call Peter when I was having a "low rider" situation with the stylus coming too close to the LP for comfort. What he said kinda surprised me: run the arm slightly tail-up (rather than level) and set the VTF at 1.4g, which he said would work fine with my arm, instead of the 1.8 to 2.2 range shown in the "manual" that came with the cart. This certainly did the trick as far as the low-riding was concerned.
