I got a quickfuel 780vs,it's on a 406 . I have a weiand team g single plane intake. I get 6-7 " vac in gear with the 3500 stall,idle I'm 8.5 3000rpm 17ish. My carb is out of box settings except for dropping mains by 4 to 70/82 rear. Stock is 74/82. It still is pretty rich at cruise ,2800 rpm I'm 12.9 13.3 with a/f gauge. My plugs show rich also. The air bleeds are 70/33 , I have messed with them some with mixed results,I'm not sure which direction to take,I can just keep jetting down and go 68 but getting far from stock,should I cut down some idle feed since my idle mix screws are all out just 3/4 of a turn to get mix screws to 1 1/2 turns? I want some better mileage , mine is about a gallon per 5 minutes of driving
