ck your primary meetering blocks see if those carbs have changeable idle feed restrictors, farthest ones out, if so try going down about .006 there, will work better than the air bleeds, my blowthru did and changes the AFR at idle easily

ok so we put some int bleeds in went down from .070 to .055 that helped a bunch but I am still having the idle issue I found this out after a 1 mile cruise run at 3500 then coming to no wake the motors idled at 700rpm no problem for like 45 seconds then they started to fall down in rpms and I had to crack the throttles a hair. I think they r rich at idle, think some bigger idle bleeds will help .040 in there now its much close with the int bleeds cruise rpm is like 13-13.5-1 seemed to help with idle slightly also I have a little more time before it wants to quit
