I have a sticky accelerator. Wd 40d it. Still sticks. Anyone have this happen? Should l start at the pedal or the motor?

    I would look under the floor where the accelerator is , the hand throttle over travel and other things are there. Have someone work the pedal. Follow it up to the engine if there is no binding there.

    same problem,any sand or debree will slip down along pedal and keep pedal from moving easy...i hooked a small bungie cord from the pedal to the signal light lever,works fine 3 dollar fix
