Hi,
I have a Holley 750 DP carb with 4 corner idle and would like some help with the procedures to fine tuning it. Im not sure about how to set the back screws in relation to front and accel pump type issues. Im sure there is a step by step to follow but its driving me crazy guessing. All help appreciated

See if this Holley instruction helps......
