Title: Dist Vacuum port
Post by: DaveD on October 26, 2011, 02:46:34 PM

From what I have read the port for the distributor is normally on the driver side above the mixture screw.
My carb does not have this port, does that mean it does not have a source for the dist?
Below is a picture of my carb.

It still used the vacuum advance.  Probably sourced from one of the other locations on the carburetor.  May have been routed thru a temperature switch first.  If you are not using all the original factory components, you can run vacuum directly to the advance.  The location just above and to the left of the fuel filter housing is full manifold vacuum.  The lower left source in the baseplate (as viewed from the front) is ported vacuum.....Cliff
