Throttle control linkage Volvo 140 (B18B)

Stiff or sloppy throttle response on a 140 with the B18B can often point to worn ball joints and bushings in the linkage between the gas pedal and the two carburetors. Since the B18B runs twin carburetors, the motion must be distributed evenly, and a worn-out control gives uneven synchronization and sluggish response. This category gathers wear parts that keep the linkage tight and predictable.
