Description
Proper jetting is fundamental to carburetor tuning—too lean and you risk detonation and engine damage, too rich and you sacrifice performance and fuel economy. The Holley 122-79 main jets deliver precise fuel metering for mid-range and cruise conditions, ensuring your carb is dialed in for consistent power delivery across the RPM band. Whether you’re tuning a street engine or fine-tuning a race carb, having the right main jet size is non-negotiable.
