1 1/2 turns out from seat should get you started. The best way I've found to set up your idle mixture is to connect a hand held vacuum gauge to the full-time vacuum port. Adjust one idle mixture screw at a time until you get the highest vacuum setting and smoothest idle. Adjust the idle speed and recheck your mixtures. I'm running dual 1405's and have success with this method. - Aggressor
