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? |

My only problem with the Cap'ns explanation is that the same size ports on the throttle body are connected. I followed his direction and connected the same size ports and that means I have no vacuum advance, only vacuum retard. I went with the expert but still wonder....
