Description
Main jets are the critical metering orifice in your Holley carburetor—they directly control fuel flow at cruise and part-throttle conditions, making them essential for achieving the precise air-fuel ratio your engine demands. Running the wrong jet size results in either a lean, sluggish tune or a rich, inefficient run. These Holley 70 jets deliver consistent fuel delivery and are a straightforward replacement or tuning adjustment for carburetor optimization.
