High-quality air corrector jet for Weber carburetors (article series 77401). The air corrector jet is a push-fit component that presses firmly into the top of the emulsion tube. It works in conjunction with the main jet to control the air/fuel mixture in the high-speed circuit. By changing the size of the air corrector jet, you can adjust when the mixture begins to lean out at higher RPMs, which is crucial for optimal top-end power and engine response.
