Re: Vacuum port for vacuum advance
Pretty sure that's the one Holley intended to be used for that purpose.
It's "ported" vacuum; there's no vacuum there until the throttle is somewhat open; not always "The Best" solution, but, a good starting point.
Try it and see what happens.
You like to live on the edge I see... rubber death-trap fuel lines. Not me.
