holley idle issues

thanks ramcharger, I just got done installing it and got the floats set, but I'm not sure of how to adjust the four screw idle mixture screws,,,any help with that??????????? :yawinkle:

air fuel should be able to be adjusted by puting a vacuum gauge on one of the ports that has constant vacuum on the carb, then screw air fuel screws in all the way then back them out a turn and a half. Keep unscrewing them until you have maximum vacuum, if vacuum starts dropping then your too far.
