Industrial P420268983

Industrial P420268983 is an aftermarket main jet for carburetors, marketed with the variant numbers 420268983 and P420268983 and identified as Jet #150. This size designates a 150 main-jet orifice used to regulate fuel flow in the carburetor’s main circuit, helping tune performance at mid- to high-engine speeds. As an aftermarket replacement, it is intended to fit carburetors that require a size-150 main jet, with exact compatibility determined by the specific model and jetting configuration of the unit. The presence of product listings labeled Main Jet 150 across supplier catalogs confirms the standardization of this jet size, and similar 150-size jets are offered by multiple brands and distributors. When installing, refer to the carburetor manufacturer's service instructions and charted jet sizes to ensure correct selection and avoid lean or rich conditions that could affect performance. This part provides a straightforward path to restoring original-factory jetting when the size-150 main jet is indicated by the service data for your equipment.
