the throttle will not move when power is applied. the motor will not let it which is normal. while the ignition is on, move the throttle cable (next to the brake reservoir) and see if the throttle moves with your inputs. if it does not, then I would suspect a possible throttle position sensor issue.
if you force the throttle plate to move with ignition on, you can strip the gears inside... I've done it.
