I'm having a little trouble with tuning my new mikuni VM22. It's on a predator 212 hemi with black mamba cam and 26# springs. I have the stock pilot and main jets in it, 30 and 100 respectively. I started with the air screw 2 turns out, started it up and adjusted the idle a little high. Then I turned the air screw in which made it about die so I went out to about 2.5 turns out which was the highest idle. The problem is that when I twist the throttle it dies. Any idea on the next step and did I do the idle screw right?
