Need help tuning AED carb

when i used a carb (750 AED HP with Aluminium main body - now EFI) i had the same situation. I could only get it to idle good with the IAB´s completely removed......after getting some blanks for the IFR´s i drilled some smaller ones (0.031" if i remember correctly, still written on the inner fender ;-)) it was MUCH better....could open up the mixture screws where they should be and put some IAB´s back in. It was a tad rich idling / cruising, could have gone 0.029" or so....did not more tuning because swap to Sniper EFI. Now it´s idling at 14.5 AFR without any trouble.

Test some smaller idle feed restrictors
