Hey Tubman....I read this...
This distributor has no mechanical advance capability and relies solely on vacuum signals from the carburetor for advancing the spark. A special version of the Holley 94 was developed that supplies that specialized signal through a port about half way up the backside of the carburetor. If you don't have that special version, the distributor advance will not function. Simply connecting the distributor advance line to manifold vacuum will not work, as it supplies the wrong vacuum signal to the distributor.

So what carb? Where might I find one? Or at least that section of the carb?
