This could be caused by a worn distributor shaft, did you have a chance to try the other distributor I sent you? If both distributors do the same "bounce" thing, then I would test for timing chain slop. (rock the engine back and forth while looking at the distributor rotor) Also note that any mis-fire will make the timing mark "jump around". DD
