Every Holley Street Avenger carb comes factory set and flowed but, using the external float adjustment with sight plugs, you can easily alter the float level to regulate fuel delivery pressure without the risk of overcompensation. The quick-change vacuum secondary can provide a 60-second modification of either 6% more acceleration or 5% more fuel efficiency. While available with manual choke, Holley offers a simplified electric choke for yet another easy adjustment to your vehicle, preventing accidental over-adjustments and ensuring great cold starts and smooth idling.
