If the free play is not within spec (3/8-1/2 in, 10-12 mm), loosen the locknut (B), turn the adjusting nut (C) until the free play is as specified, then retighten the locknut.
With the cable properly adjusted, check the throttle link to be sure it opens fully when you push the accelerator pedal to the floor. Also check the throttle link to be sure it returns to the idle position whenever you release the accelerator pedal.
