Balanced blades is a good start to any head setup......good point whirley. Which Blade are you trying to set up?? The blade CP or the CP Pro? the screw on top of your rotor head holds it in place, it has nothing to do with tracking. Another place to look for tracking is your flybar and paddles. That usually will cause more of a vibration if out of balance, but it may be small enough to look like a tracking issue. Take the blades off, remove the tail motor wire from the 4 in 1 and spool up slowly to about 1/3 to 1/2 throttle. If you see any vibrations while looking down on it, then it could be your flybar.
Main shaft is straight and good to go??
Feathering shaft is straight? If you experienced a crash, the main shaft and spindle might be your culprit too. Keep looking........it will be the last thing ya try that fixes it! I am still trying to find that last thing on my CNC head setup, but I know it will come!
