carb trouble
hello everybody, i have 327 motor, 9.1 CR, comp cam {274-286} {230-236} {487-490}, vortec cylinder heads, edelbrock vortec performer rpm intake, 575 demon mech sec carb, pertronix flamethrower hei ignition, turbo 350 trans, 2800 stall, 4.10 gears. car is running so rich at idle, it will burn your eyes, it has a new power valve, and i know what the vacuum is, so i know it is not opening, the front idle mixture screws have hardly any effect, i have 18 initial timing with vacuum advance plugged, then when i hook it back up i have 44 at idle, i run manifold vacuum for advance, does that seem like to much? any suggestions?
