Carburetor adjustment for the 4 barrel/390
Can anyone tell me the basics to adjusting your 390/4 barrel motorcraft carburetor. The adjustments that I know of are Choke, Idle, Air screw. Where should the choke be set to ideally? Can the Idle be adjusted by ear or is there a guidline to go by? If I'm facing the engine, what does the air screw to my left do? When you screw it in is it giving more or less air? Same question but for the right?
