Idle problem
I own an 85 F150 that runs really rough. I just changed the plugs wires and distributor cap and rotor. It seems to run a little better now but the idle is too low. I have examined the 4-barrel Holey carb from every angle and I can't figure out how to adjust my idle speed. Any suggestions?

Idle problem
The 4 barrel holley has a screw on the side front drivers side of the mounting base.Make sure it is the one that screws into the base,not any screws that are part of any linkage.When you have the right screw, you will notive how the throttle lever contacts the tip of the screw when resting.I would like to suggest that if you ever remove the carb,or have removed the carb recently, to change the EGR Spacer Plate gasket under the carb.This gasket is often forgotten as a source of vacuum leaks.
