    You will find an extension on the side of the distributor with a large hex nut. There is a bolt that is threaded to this large nut. If that assembly is removed from the side of the distributor you will find the plunger inside.
    Its purpose is to inhibit the amount of advance in the distributor by rubbing against the advance mechanism in low vacuum situations. When vacuum increases the advance is allowed to progress. The bolt is the adjustment for how much tension is present to inhibit spark advance.

      Does a vacuum line screw into this port?

        Yes it does. The vacuum line comes from a port very close to the two left side rear intake ports.

            The real question is do you know how to set the distributor up?

              Vacuum leak or lean mixture Detection
              by Mitch
              Another easy method to try is if you have a vacuum wiper, just remove the hose off of it. Then spray a shot of carb cleaner in using a straw to see if it picks up the engine.

              Ford Model A Vacuum Wiper Motor
              by telmore1964
              I am thinking I would like to have my truck as original as possible and thinking about going back to vacuum wipers. I can't tell for sure if this truck ever had the vacuum motor installed because the holes that are already there don't seem to line up with Trico wiper motor mounting holes. Also on the outside of the window frame there is no hole large enough for the vacuum hose and on the inside of...

              31 Vacuum line
              by JohnB15632
              The vacuum line that originally cam with my Model A is plugged solid.
              Any ideas how I can get this tube unplugged?
              Would it be better to try to manufacture/bend a new vacuum line?

              Thanks,

              Drilling a Hole in a Round Shaft Can be Easy and Accurate
              by Tom Wesenberg
              Let's say you buy U bolts to secure the rear spring, and they come too long, so you cut off the extra length, but now you need to drill a hole for the cotter pin. Buy a hex nut and scribe crisscross diagonal lines across the 4 corners of one flat side. Now center punch the exact center of that flat, which is where the lines cross. Clamp the nut in a drill press vice and be sure the flat is perfect...

              What are the Specs of Your engine?
              by Tom Wesenberg
              If your engine is in good condition right now, then it's a good time to check the compression, vacuum at idle and higher speed, coolant temp, and generator volts.
              Write these down and keep them with your car, then you have a good basis to check against when something goes wrong.
