Sluggish throttle response, play in the pedal, or a linkage that hangs up during warm-up are usually caused by worn ball joints, dry bushings, and a gaswire that has begun to bind in its sleeve. This category gathers control parts for the B20B/D of model year 1973-74, where the carburetor control places its own demands on play and friction in the linkage.

The group includes the gaswire, ball joints, and bushings for the link points, plus nuts, washers, screw, and coupling that hold the mountings in place. There are also knobs for the control here. During a rebuild it is worth checking the ball joints and bushings at the same time – a single worn-out joint play gives uneven throttle response and a hard-to-set idle on a carburetor-fed B20.
