Does anyone know how the vacuum diaphragm on the distributor works?
One side is to retard the timing correct? does the other side advance it as the vacuum drops or changes? Should I have noticeable vacuum on that hose when I pull it of the diaphragm? |

The 74 cars, and some later ones, do not have vacuum advance. They have the fitting on the distributor dashpot, but not the one on the throttle body. So there's a good chance the setup that puzzles you is the stock setup.
