While am finishing the 3x2 94's on the 57 Bird I am using a Holley 4bbl list #1848. This is the replacement carb sold by the Tbird restoration parts companies. The carb is about 6 years old. I have the vacuum advance line from the distributor connected to the port on the upper passenger side on the front metering block. This port has vacuum at any idle speed. Is this right? I am fighting a bad hesitation.
