"VAcuum advance". Step on it, vacuum goes down and it advances timing for more performance/power. Idle of letting off, advance goes back to setting for economy.
A vacuum leak nearby. Distributor shaft & bushings are worn and the rotor is clipping the distributor cap inside. Spark arking inside cap.
It won't. That vacuum line tells the distributor When to advance the timing. There isn't enough vacuum loss to stall an engine.

It depends on which distributor and transmission you have. The stock distributor has one vacuum line going to it. An autostick transmission has one line. If you have a manual transmission and a Bosch 009 distributor like most people do, you have no vacuum lines.
If you have a manual transmission and a centrifugal advance distributor, you don't have any. If you have vacuum advance on your distributor, there's one vacuum hose running from the side of the carb to the distributor. If you have an automatic transmission, you've got a hose from the intake manifold to the control valve.

If it is a point type distributor you will want to hook it to constant vacuum...somewhere on a port in the base plate. If it's HEI you'll want to hook it to one in the carb body. Something that has no vacuum at idle but pulls vacuum as you give it throttle.
vacuum advance can connect anywhere there is vacuum present,carbuerator base is a good spot
NO. It needs ported vacuum. This means that it should only have vacuum on it when you bring the rpms up off of adle.
at the distributor. mechanical type
Detach the vacuum hose from the vacuum advance unit. Remove the distributor cap and unscrew the two mounting screws. Pull the rotor off the shaft and remove those two mounting screws as well. Unscrew the two advance unit mounting screws and remove the unit from the distributor.
Could be vacuum module in distributor or other vacuum
