1959 twin wcfb

How does one tune and adjust a two four barrel wcfb setup on a 1959 corvette?

John -

For my 2x4's, I always got a #755 vacuum fitting from Paragon and installed it in place of the stock plug in the rear of the baseplate on the rear carburetor, to use as the source for my vacuum gauge so I could adjust the idle mixture screws on both carburetors. Just put a rubber cap on it otherwise.

The 1961 Passenger Car Shop Manual (available from the on-line store here, button at the top of the page) has all the WCFB 2x4 tuning/adjustment detail info - there's nothing in the ST-12, as the same setup was used on the passenger cars.
