You need to understand why you are making it adjustable. Is the problem at cold control pressure or warm cntrol pressure? Then to do the adjustment, you need to measure the control pressure with the fuel gauge connected. Plus the control fuel pressure is related to the system fuel pressure.

I've been following your troubleshooting saga and it would be very difficult to correct your problem/s because you don't know what's causing it in the first place. The pin you are showing is the part that pushes up the metallic diaphragm inside in the WUR. That is not the pin used for adjusting the cold control pressure.
