Hey all,
I asked a question on an old thread and maybe I just need to start a new one: On a carbbed car, what is/are the advantages of a vacuum advance distributor, if any over mechanical? Or is it the other way around? What reasonably priced solution should I use? (IMG:style_emoticons/default/confused24.gif) I am pretty sure mine is vacuum challenged and needs replacing (my mechanic says I should replace it and seek advice from the 914 experts, since he is a fairly talented generalist) (IMG:style_emoticons/default/idea.gif) Thanks Sean |

QUOTE(jcd914 @ Jan 5 2012, 08:11 PM)  Your carbs will need to have a "ported" vacuum fitting for the advance. Most aftermarket carbs do not have this out of the box. It is a percision drilled hole with a vacuum hose nipple. The hole is blocked by the closed throttle plate and progressively gets vacuum as the throttle is opened. Jim Are you saying that if I buy a set of Weber 40’s it will not have a “Ported Vacuum” out of the box?

Aircooled.net offers installing a vacuum port as one of their services, in addition to cleaning and custom jetting carbs for your engine and altitude. They also sell SVDA Dizzies. That's the route I'm looking at, for a minimum of fuss. Haven't bought it yet, but I hear good things about them.
