Description
Main jet sizing is critical to carburetor tuning—get it wrong, and you’re either running lean and risking engine damage, or running rich and leaving power on the table. The Holley 122-60 main jets give you precise fuel metering at cruise and part-throttle conditions, ensuring your carb delivers the right air-fuel ratio across the RPM band. If you’re dialing in a Holley carb for street or strip duty, upgrading or replacing worn jets is one of the fastest tuning adjustments you can make.
