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.

The group includes screw, nut, ball joint, bushing, cotter pin, lever, washer and retaining clip. During a rebuild, the ball joints and cotter pins are typical checkpoints – replacing them at the same time gives you back precise, play-free throttle response. Always check that the parts fit the B18B setup, since the linkage design differs between the carburetor variants.
