Tunnel ram or no tunnel ram...

I talked to the builder of these carbs and have exact numbers now: IFRs are 0.033" and main body restrictors are 0.052"
He suggested to put smaller MABs, there are 39s in the carbs. He says I have a weak booster signal problem so no fuel is drawn thru. I really dont know what to say. I think I have 32 and 34 MABs to try...
