My 71 Charger 500 has 383 Magnum engine, I recently had an issue with base filling with gas due to leakage of the old Carter AVS carb, always been a fan of Holley so I replaced with Holley street warrior 600 CFM, vacuum secondaries, electric choke, single feed, engine performs quite well on throttle, but runs too rich at idle, and idle a little sketchy, tried adjusting idle mixture screws, but were set fairly close from factory, did adjust idle speed though. Contacted Holley tech and he said he thought I should run at least a 650 cfm, but may get away with what I have, anybody got any suggestions.
