Description
Precise fuel metering is the foundation of carburetor tuning, and these Holley main jets are essential for dialing in your air-fuel ratio under load. If you’re experiencing rich or lean conditions at cruise and wide-open throttle, swapping jets is one of the most effective—and affordable—ways to optimize performance. Whether you’re building a street engine or fine-tuning a race carb, having the right jet size ensures consistent, repeatable fuel delivery.
