With that aftermarket mechanical secondary kit, you also lose having a fast idlse when on the choke. The lever on the carb that is pulling the secondaries open, is the lever that normally has the screw adjustment that hits the fast idle cam on the choke.
Probably why the carb pictured has all the choke parts removed. Good for warm weather I guess, but would have to warm up a little without a choke to idle decent.
