WHoa, hold the phone! Your EGR valve has a little 1/4" or so port on it,
you have a hose from this going to the distributor vacuum advance??? Way
wrong if so! No air will flow at all!
On the 150CD there is a port on the body upper body area near the mounting
flange. This is for the EGR. There is another port on a brass extension
coming off the toward the bottom of the carb - this goes to the Vacuum
advance.
