when I turn the mixture, it seems to do nothing. I have the extra X92 (CA cars), and I've followed the link above, and the volt meter reads a steady 12v. I've turned it at least 4 complete turns both ways, and nothing seems to change, not even the sound of the idle. It's back where it was now.

I'm pushing down and I feel it engage. Push too much after engagement, and yes it will drop in idle.

You know what, turning the mixture screw should just move the top plate up or down, it doesn't do that, I should at least see that, with 3 + turns in either direction! If I push the top throttle plate with my finger a little, then idle changes, like it should.

I wonder if that screw is stripped??? I might have to take the whole little tower off....

Are you using the correct size allen wrench? Are you pressing down when you turn the adjustment screw?
If you get it to work, make sure you turn it just slightly to adjust the duty cycle.
