Description
Proper jetting is critical to carburetor performance—get it wrong and you’re leaving power on the table or risking a lean condition that damages your engine. The Holley 122-88 main jets deliver precise fuel metering at cruise and part-throttle, ensuring your carb stays dialed in across the RPM range. Running the correct jet size for your engine displacement, fuel type, and altitude is non-negotiable for consistent performance and reliability.
