Description
Precise fuel metering is the foundation of reliable carburetor performance, and worn or incorrect main jets compromise both throttle response and engine efficiency. These Holley main jets deliver the exact fuel flow your carb demands at cruise and part-throttle conditions, ensuring your engine runs lean enough for economy but rich enough for consistent power. If you’re rebuilding a Holley or replacing jets due to jetting changes, this matched pair eliminates guesswork and restores predictable performance.
