Micheal , drawing attached should explain, they are common on the throttle body of many cars now, I know my 90 300zx has two of them, at idle throttle opening is slow due to the longer 'A' distance, while at around WOT the 'AA' is shorter & faster. Dotted line is throttle cable as it wraps around the 'drum'. In your case you would mount this drum on the center cross shaft and rearrange the links to each carb so that they open the primaries together.
