Throttle control linkage Volvo 164 (B30A) (-1972)

Play in the throttle linkage and a gas pedal that feels sluggish or sticks are classic symptoms of worn ball joints and bushings in the control. On the 164 with the B30A carburetor engine, there is a mechanical rod system that develops play over the years, which can cause uneven throttle response and a hard-to-adjust idle – the ball joints and grommets are therefore worth checking during a restoration.
