Today was starting from the ground up and getting the primary idle circuit correct. Yesterday it was running so rich when I first tried it out, and it was choking out when I hit the secondaries. Today all I did was take those heavy number seven Springs out and put the yellow Springs that I had in my old Edelbrock in there and it was instantly and major difference.. I counted the turns on the idle mixture screws and the rear carburetor had one and a half turns out and the front carb two turns out.. I turned the fronts in a half turn to match the back and picked up a little bit of idle and got a little leaner.... Just changing the springs the wideband O2 up about two and a half.. yesterday it was running around 9 barely 10 and today I was seeing hi 11 12 and 13's.. another thing that O2 sensor was going a little crazy...
