The secondary air valve is also easy to adjust to tailor the opening rate to your engine.These carbs are somewhat similar to a Rochester Quadrajet, but the AVS's larger primary throttle bore gives a more powerfull response at part throttle openings and doesn't have a rich idle problem often found on Q-jets.The CFM rating is around 650 cfm. | | |
