Description

Main jet sizing is critical to carburetor tuning—get it wrong, and you’re leaving horsepower on the table or risking lean-out conditions that damage your engine. The Holley 122-105 main jets deliver precise fuel metering at cruise and part-throttle operation, giving you the control you need to dial in your air-fuel ratio for optimal performance and reliability. This pair ensures both primary and secondary circuits run consistently, eliminating the guesswork from carburetor calibration.
