Carb Tuning?

My question is about the two screws to adjust the carb. If I wanted to start from scratch, both screws in all the way. How many turns do I need to start. There is a big screw and underneath there is a small screw.

thanks

Top screw is the idle air adjust and the bottom screw is the idle mixture adjust. Make sure ignition timing is correct. Also, I wasn't able to acieve a real smooth idle until DLDFIS upgrade. Start with both screws out one full turn from closed position. Ajust mixture screw until idle is smooth. Adjust air screw to set idle speed. May need to go back and forth a few times.
