You should have 1.5mm freeplay in the cables. Push the cable inner up/down between pulley end and the cable holder to check the slack. Better slightly loose than too tight.
You won't be able to rotate the valve easily with pulley and cables attached because you'll also be trying to move the servo motor itself.
To set the pulley position and cable slack correctly follow this sequence.
Step 1. With ignition OFF, turn the pulley fully clockwise with an 8mm spanner on the pulley bolt. The fork should be pointing to around 2 o'clock or thereabouts.
Step 2. Turn the ignition ON. The valve will reset to the 'parked' position. Turn the ignition OFF again and look where the fork is relative to the alignment hole in the end plate.
If necessary, slacken one or other of the cables to enable you to align the fork over the hole. Pin the pulley in place and set the correct amount of slack on each cable.
Repeat the first two steps again to confirm the alignment and correct slack.
