One New Aftermarket Replacement Carburetor Main Jet Fits Briggs and Stratton (Fits Briggs & Fits Stratton) Small Engines
This carburetor main jet (Jet-Main) is an aftermarket replacement Fits Briggs and Stratton small gasoline engines used in lawn mowers, riding tractors, generators, pressure washers, and other outdoor power equipment. The main jet is a precision-machined brass fitting located inside the carburetor float bowl. It meters fuel flow into the engine and is a common service item when an engine runs rough, runs rich, or fails to start after sitting with stale fuel. Ethanol-blended fuels can corrode or clog the main jet over time, making periodic replacement an important part of carburetor service.
