Per CMA, there is no need to disconnect the vacuum lines.

Also per CMA, the first thing to do is to close each air correction screw by turning it in until it is lightly seated. From there, open them up one and one half turns before proceeding. That is your starting point.

Once you have them balanced, set idle speed on a warmed up engine by turning all six of them equal amounts. Turn them in to slow down the idle, back them out to speed it up.
