I would say that the addition of the pan is changing the way the air is passing over the idle air bleeds.
If you run the motor up to 3000 rpm with the base on and off does the overall mixture stay the same both ways?
Also if you drop on the air filter and lid does that same Mixture change happen?
On any car/ motor you want to only adjust the mixture screws with the whole air cleaner assembly on anyway, if you need to then a flexible long idle adjustment screwdriver is needed,
