RMC List - Where does this go?

[JOHN DAWSON]

Is your car a 68-69 or a 66-67 AIR CA car?
Does the screw have a flat screwdriver slot on the threaded end? 
If so, then it looks sort of like the off-idle air bleed screw that fits into a spot in the throat of these carbs.
If it's not in place, then you could be experiencing the off-idle richness you describe.
 
Happy motoring
John Dawson

This carb goes WAY rich at very low part throttle at road speeds(visible black smoke on that side that incan see in the mirrors). That carb idles fine and otherwise runs great. I can see the cluster dumping gas if I look down the bore and just crack trh throttle open.
