Throttle linkage Volvo Amazon (B20B)

Play in the ball joints and worn levers give uneven throttle response and a pedal that won't return cleanly – classic symptoms of a tired throttle linkage. On the 122 with the 118 bhp B20B (in the range from August 1968 during the model's last two model years) the control sits mechanically between the pedal and the carburetor, and every bit of play in the joints is amplified out to the throttle.
