The linkage is now ready for adjustment. All three carburetors are opened to wide-open throttle simultaneously. The furthest throttle stop collar is slid against the front carburetor link pin and the 5/64 setscrew tightened. The carburetors are then set back to idle position. Then the middle throttle stop collar is slid up to the same front carburetor link from the other side and lock it down. The linkage now has a good base adjustment.
