Do you mean your motor height?
If that is that case.
1. Insert the motor, careful not to catch the wires directly underneath or on the sides of the motor.
2. Screw in the Motor Plate screws, keeping firm pressure on the motor plate, making sure not to let go until both are in place.
3. Screw the motor plate's motor screw lightly clockwise, you should feel some resistance and then the screw will not turn, don't force it.
4. Turn the screw counter clockwise once. Pull the trigger, it probably won't fire. Turn it in half counter clockwise half turns until it fires.
5. Find the sweet spot, Once your gun is firing in semi, find the spot which SOUNDS like it's not chewing up the gears, it's a hard sound to find. Go clockwise and counter clockwise until you feel the motor is sitting happily.
It's a hard sound to hear for, but you will hear it eventually.
Good luck to you.
NOTE: Do all of your testing with your trigger set to semi-only. Holding the trigger down on auto with a locked motor can fry wires, blow fuses, and ruin your motor. I hope that puts the fear of God in you.
