Briggs Stratton 595922 Main Jet Carburetor Part

Product Description

The BRIGGS STRATTON 595922 is a genuine OEM main jet designed for use in small engine carburetors. The main jet is a precision-metered orifice component that regulates fuel flow into the carburetor venturi, directly affecting the air-fuel mixture delivered to the combustion chamber. At 0.39 inches x 0.39 inches x 0.39 inches and weighing just 0.02 pounds, this is a small but functionally critical part. Correct jet sizing is essential for proper engine performance, fuel economy, and emissions compliance. This is a factory-original component, not an aftermarket substitute.

Main jets are replaced during carburetor rebuilds or when an engine exhibits symptoms of fuel delivery issues such as running rich, running lean, rough idle, or poor throttle response. This jet is suited for residential and light commercial small engine applications including lawn mowers, generators, and similar outdoor power equipment powered by Briggs Stratton engines. Installation is typically performed by small engine technicians or experienced equipment service professionals.

Installation Notes

Main jet service is performed by small engine technicians as part of a carburetor cleaning or rebuild procedure. Shut off the fuel supply and relieve any residual fuel pressure before disassembling the carburetor. Use properly sized screwdrivers or jet removal tools to avoid stripping the jet seat or damaging the carburetor body. Confirm the replacement jet part number against the engine model and type code before installation to avoid fuel delivery issues caused by incorrect jet sizing.
