Installation and tuning of the six pak induction system by Jerry Binder says the opposite to the above link in the post above. Which is right which is wrong?

I have only made minor changes to the outboard baseplate screws on any of my stuff, but it did help after upgrade of cam. (had to turn each of the 4 outboard screws less than half a turn for me) I converted an old mixture adjustment tool, the 45 degree ended kind with knob on top, so that it could get in the 6 pac end carb recesses while on the car! works nice.

It looks divided on opinions. Its ineresting some say when idle increases mix is lean others say mix is rich.

Sorry Guys, I apologize,....I flubbed when I typed the air bleed lean/rich technique when I wrote that sentence, should have remembered the old addage when blocking off the air bleed. if it "sounds mean(high RPM) it's lean, if it's ragged (low rpm) it's rich" ......but regardless of the flub, the idea is to try and minimize the rise/fall in RPM when blocking the outer bleed and turning the corresponding base screw to achieve the ideal air/fuel ratio based on rpm readings, again I apologize for that flub Mike

Study and understand carb function, and you will know which is correct.

When you block off an air bleed you enrichen the mixture so it is lean? I would start with the outboard idle screws out 5/8 turn from seated and go from there. Then tune the outer carb since you can get at the screws with it on the engine and then switch it with the back one and adjust it while running. Al & Sheila

I'll look for a matco catalog for more info.

Cut it about 22" long, straightened it out & flattened one end like a small screwdriver & bent the other end 90 degees for a little twisting lever.
