Weber Idle Jet

0.40 / F9 (40/45/48 sidedraft)

Weber calibrated idle jets are a legendary component that meters air to the emulsion tube well. Weber is without question the most popular for performance applications. In good tune, the results are excellent. We recommend Weber jets for the high performance, value and increased fuel efficiency. The only way to get maximum performance is to tune your carburetor for the unique needs of your engine. You should also make adjustments for altitude and weather changes. We also offer kits to assist you with tuning.
