Carburetor Idle Transition Slots

After getting to the bottom of the last issue, I yanked the carb off so I could reset it and go from there to make sure the idle is dead right next time.

When trying to set the idle transition slots to the .020", the primary went just fine.

However, I can have the secondary curb idle screw all the way off the adjuster to the point that there is over .020" between the curb idle screw and the shaft adjuster, and the secondary blades with a simulated return spring on the throttle lever expose over .047" of the transfer slot (my .024 and .023 feeler gauges stacked on top of each other). According to Demon (and Holley), this slot should be totally covered by the secondaries, but I just don't see how that can possibly happen when there is a throttle return spring on the carburetor.

Now..when I open the throttle, the blades do drop and cover the transition slot fully before reopening. Is this typical? I would like the car to idle somewhat correctly without having to buy a whole new carburetor.
