Briggs Stratton 597495 Main Jet Carburetor Part

Product Description

The BRIGGS STRATTON 597495 is a main jet designed for use in small engine carburetors. The main jet is a precision-drilled fuel metering component that controls the volume of fuel entering the carburetor's main circuit during mid-range and high-speed engine operation. Proper fuel metering is critical to engine performance, fuel efficiency, and emissions compliance. This part is installed by small engine technicians and qualified service professionals working on outdoor power equipment powered by Briggs Stratton engines.

This main jet is suited for residential and light commercial outdoor power equipment applications. Typical install scenarios include carburetor rebuilds or replacements on lawn mowers, riding tractors, generators, and similar small engine platforms. It is a direct-fit OEM-style replacement component intended to restore correct fuel delivery in carburetors that exhibit lean-running conditions, fuel starvation, or carburetor wear.

Installation Notes

Main jet replacement is typically performed by a small engine technician during a carburetor rebuild or cleaning service. Shut off the fuel supply valve and allow the engine to cool completely before beginning carburetor disassembly. Use appropriately sized screwdrivers or jet wrenches to avoid stripping the soft brass jet body. Follow applicable small engine service guidelines and local emissions regulations when servicing carburetor fuel metering components.
