Throttle control linkage Volvo B16 (Early 445)

Play in the accelerator pedal, sluggish response or a throttle wire that snags can often be traced to worn ball joint shells and stretched linkage parts in the carburetor control. On the early 445 with the B16A motor, the throttle control works mechanically against the Zenith or twin SU carburetor, and every bit of play in the joints means poorer metering at idle and part throttle.
