Secondaries are only operated by the vacuum, no mechanical action on this setup. However, if you are able to develop more throttle/rpm by moving the throttle cable connection point, and a consequently a higher vacuum, then they would open more/wider. There are also several different springs that can be used within the secondary vacuum assembly to alter when they start opening.
