I have a 318 with edelbrock heads , weihand DP intake and 204/214 flat tappet hyd cam. Has 9.8 to 1 comp. The AVS2 runs at idle only 3/4 turns out on idle screws so seems a bit rich. I have drilled a 1/16 holes in the throttle blades and adjusted the transfer ports to square but still seems rich at idle. I have also went one stage leaner on the main jets but correct me if I am wrong but this does not come into it at idle. What can I do to correct this and is anyone findind this the same...
AVS2 650
