That's what I do, & if you drop it carb has to come off.

 I'll probably pull the carb off to swap any of these just to be safe. I've got the process down to a couple of minutes and two tools.

 What transition are you referring to here? How does this work exactly?

 

77cruiser:
Transition slot, smaller AB will richen idle curb idle can leaned out with the screws.

Kenth:
I have found that the idle/low speed mixture is predetermined by the idle tubes/jets and the upper and lower air bleeds and any idle bypass air.
The amount of mixture, on the other hand, is determined by the channel restrictions and the mixture screws.
The off-idle slots acts like additional air bleeds above throttle blades and changes to idle mixture discharge nozzles when thottle blades passes the slots at greater throttle blades openings.

So you cannot get a leaner or richer mixture from the mixture screws at idle, only more or less volume of the mixture.
