Default carb rich problem

Hello to all ! I have a problem that my Dyno tune guy doesnt have an answer to. I would appreciate any input. pardon me but I will explain it as best as I understand it.

My car is running rich while cruising between 2000 -3500 rpm's.
My car runs at about 14.2 at idle , 12 between 2000-3500 and back to 13.2 under full load(when the secondaries kick in)

I have a 428 motor, 2 - 600 vacum secondary Holley carbs, factory type progressive linkage , High performance carter fuel pump (9 psi and drops to 7 psi under load), CJ heads that are reworked, 524 lift cam, 248 duration, MSD 6al system, 10.5 to 1 pistons.

My Dyno guy said the carbs are out of the idle circuit but have not hit the power circuit in my condition. So the jets (66) have not come into use yet. My car pulls 9-12 psi vaccum while idling.
I hope this makes sense. Thanks for any input. olaf herrick
