383 dual quads lean at idle and cruise

on any dual four , the rear carb is main one, the front carb, isn't used for idle,.

Thanks I will look in stagger jetting if this doesn’t fix it. The rest of my parts should be here today. Also linkage is 1-1 not progressive. I have been adjusting the carbs with the linkage disconnected and adjusting the idle down equally between the carbs and then centering the linkage when done
