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.
