Sounds like the short hoses are crossed. You sure they aren't?
As for the adjustment, you are tightning down the nut until all the parts inside the centering spring have collapsed and bottomed out together. Any more and you may snap the retaining pin on the end of the threaded rod. The approximate amount of tightning is "real snug".
At this point you want to mark the end of the bolt and the nut. There is a lot of play in the bolt, so you can almost turn the nut 1/4 turn before it actually starts backing off the bolt.
Take out all the slop, then watching the marks you made, back off the nut 1/4 turn on the bolt.
This adjustment sets the bias the system has for turning left or right. If it is off, the system will want to power itself more one way than the other. It shouldn't have any effect on the problem you describe, or the pressure in the system.
If you still have this problem, and the short hoses are hooked up correctly, then something else is messed up in the control valve.
