Sector gear timing

My new ctw stops in the wrong spot on semi auto. The teeth are to high causing me to not be able to breach the weapon.
Anyone know how to get the sector gear to stay down?
Is this a common problem?

Fire once on semi, then fire on auto, then semi once, and it should be alignied, and you should be able to close the gun.

Thanks , that is what I thought too, but it isn't working. Still keeps stopping in the Wong position

some things to check:

1. are the holes in the sector gear clear ... there are "eyes" on the main electronics board that read the position of the sector gear through those holes

2. check the main board "eyes" for obstruction

3. does the sector gear spin freely, try to move it with your fingers to see if you can make it move. If it does, your BEVEL gear has seperated

also the momentum from the gear makes it move farther then it should.. it has a little more power behind it then a systema, that is why sometimes it goes further then it should.
