I have a '75 that has no EGR valve, but has the vacuum advance distributor
with mechanical points.
I believe the vacuum line from the distributor goes to a vacuum port on the
bottom of my carb.(CD150 Zenith Stromberg model.)
Seems to work O.K., the PO did the change over. I still pass the state's
emissions test with flying colors!
