340 6 pack. I have a few references on this, but they contradict each other. When trying to set the front and rear carb it says to disconnect the linkage then place a finger over the outer air bleeds. You want to get where there is no change in idle when doing this. One source says if idle increases when you do this it is too rich and to turn the screw clockwise. The other source says the complete opposite that if idle increases when doing this it is too lean and to turn it counter clockwise. Which is correct?
