My '70 Challenger has a '71 440 with a Carter AVS 4966S carburetor. The idle speed screw or throttle stop whatever it is called threads through a plastic piece inserted into the lower carb body (see pictures of yellowish piece). This plastic piece has broken on my carb and the idle speed adjustment can change as the plastic (and screw) slides away from the throttle cam.
Anyone know where this plastic piece can be found for replacement?
