Is your pinion set screw tight on the motor? try putting a flat spot on the shaft with a dremel. Try tightening the slipper all the way and seeing if it moves then? Is the slipper warn out? When you try going and it doesn't move what IS it doing? Motor free reving? See if the shaft is spinning inside the pinion, if not then try tightening the set screw or putting a flat spot on the shaft. If thats all good next in line would be the slipper. Is the shaft the slipper is mounted to spinning? If not it points to a faulty slipper, if it is then my guess is something in the tranny is shot.
