(390 fe, hei dist with msd 6a, comp cams CCA-CL33-224-3, 7105 edel intake, 670 quick fuel brawler, fmx transmission) I recently put a new quick fuel carburetor on my engine after not being able to fix my off idle hesitation with a street avenger. The carb runs great except for it seems unusually rich at idle, it starts to chug some after a while at stop lights and it soots up the pipes and anyone behind me, its below freezing and I dont even need the choke to start it. It idles at the right rpm, 700 in park and about 500 in drive, timing is set around 16 at idle, which is what ran fine with the previous carb. I already increased the idle air bleeds from 27 to 31, and each of the 4 screws are 1 and a quarter turns outs. I know if it's rich i should move them in, but with already having bigger than stock air bleeds, I would assume they should be wanting to move out more. The transfer slots are set to a tad bigger than the stock adjustment, still mostly squares. I already replaced the power valve, it has a 7.5 while pulling about 14-15 vacuum. the floats arent too high either, set right in the middle. Any Ideas about this are appreciated, thanks.
