1933 v8 distributor Plunger?

[ClaudeC]

Where does this plunger fit in?

[Russ/40]

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?

[Russ/40]

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?
