Your shim job may have been too tight. Re-assemble the mechbox without the piston and spring and use your finger to spin to the sector gear. It should move without much effort, if it doesn't move or it requires a lot of force to move, you have shimmed it too much, remember when you screw the mech box together it tightens it up quite a bit. Also on the motor plate, if you tighten the screw that pushes the motor plate in too much, it can also cause the same problem.
