Qjets, holley, AFB's all easy to tune. Make sure all vacum lines/ports are plugged or used.
1- make sure your timing is set correctly
2-set the base idle speed 750ish in neutral
3- #1 idle screw, turn it out or in until max rpm is gained, the turn back in till rpm drops 10-20rpm
4- reset idle speed 750 rpm
5- #2 idle screw same as #1
6- reset idle speed again to 750
The rpm speed at idle is for a stock to slightly cammed motor.
In gear it should beat about 600rpm.
Hope this helps bud if not come on out to Exshaw
