At first glance this is an easy fix;
Tell me if I got this right;
You are running full manifold vacuum to the V-can,and
you set the initial to 14,and
Then you set the idle speed to what? 650 to 700?
Then you set the mixture screws for best idle,, and
now it idles at 19inches in Neutral/Park.
And you have a stock low-stall TC
Is that correct?
