Where do I hook a vacuum meter to the Carter 4-barrel on my '57 Bel Air? Only place I see a vacuum line is to the vacuum advance on the dist. Thanks.

There is also a large 3/8" NPT fitting on the middle rear of the base plate that is used for the power brakes. That one is full vacuum. The one for the distributor does not give full vacuum at idle, but only after the butterflies move a little. I know many will disagree, but they have not looked at a Carter WCFB carb. The shop manual also confirms this too.
