well is it 2 or 4 barrel-2 I'm guessing-should be 1 or 2 idle mixture screws-adjust them to the highest idle-use a tach if you have one-uh what else-choke is it manifold temp or electric????then there is high idle-on the idle speed should be 2 screws?? one is- for hot one is for cold-am I getting close with out pulling out one of my manuals?-one should have a cam on it-looks like a half moon with ridges that should be your cold adjustment-may have both screws on one??the one needs to be adjusted for cold idle the other for hot-cold hit the accelerator-it should engage the choke-1 screw should hit a detents or notches on the cam-that is the cold idle-once it warms up-the second screw should keep it running at recommended rpms-choke may have different settings??start in the middle and work your way up or down as needed
