Briggs Stratton 694250 Main Jet Carburetor Component

Product Description

The BRIGGS STRATTON 694250 is a main jet designed for use in small engine carburetors. The main jet is a precision-metered orifice that regulates fuel flow into the carburetor's main circuit, directly controlling the air-fuel mixture delivered to the engine during mid-range and full-throttle operation. This is an OEM-specification replacement part sourced from Briggs Stratton, intended for installation by small engine technicians and qualified service professionals performing carburetor rebuilds or fuel system repairs.

This main jet is suited for residential lawn and garden equipment powered by Briggs Stratton small engines. Typical applications include walk-behind lawn mowers, riding mowers, and similar outdoor power equipment where the original carburetor requires jet replacement due to wear, clogging, or damage. Install this part during a full carburetor service or as a targeted repair when fuel delivery issues are traced to a worn or obstructed main jet.

Use proper small engine carburetor tools and follow the equipment manufacturer's service manual for torque and reassembly procedures.
