Parts for Briggs & Stratton 12E702-0691-99: Gasket Sets Parts

This is a carburetor overhaul kit for 3.5 to 4 HP Max Series Quantum and 5 HP Industrial Plus Engines. It is secured to the side or top of a lawnmower engine, depending on the manufacturer. The carburetor is crucial to the overall performance of an engine because it is responsible for mixing the right amounts of air and fuel. The fuel from the fuel tank flows through a hose into the carburetor, which allows it to drip into a bowl. The carburetor can become dirty or clogged over time for a variety of reasons. When this happens, it is often a good idea to take it apart and replace the components inside. There are other telltale signs that the carburetor needs an overhaul or repair. These include an engine that won't start, an engine that's running lean, an engine that's running rich, and one that's flooded. This high-quality carburetor overhaul kit comes with everything needed to repair or rebuild a carburetor, including gaskets, needle, float, seals, and an instruction manual. Aside from lawnmowers, it works with specific models of leaf blower/vacuums, generators, pressure washers, wood chippers, and small engines from Briggs & Stratton, Craftsman, Cub Cadet, Lawn-Boy, MTD, Murray, Simplicity, and Toro. It is an OEM product sourced directly from the manufacturer and is sold individually. Please refer to the diagram of the specific model for the correct location and application of the components.

The carburetor has a float valve to control the flow of fuel from the tank to the reservoir. A float valve has three main components - a float, seat, and a needle. When there is adequate fuel level in the carburetor, the float will rise, prompting the needle to close against its seat and prevent overflowing. If the float valve is malfunctioning, it may overflow the carburetor. In some cases, it doesn't provide ample fuel into the carburetor. If you suspect that the needle and seat are faulty, don't waste another moment. Over time, a defective needle and seat can lead to more expensive repairs like a leaking carburetor and even an engine misfiring. For a genuine OEM replacement, get this Midwest Engine 398188 Needle & Seat Kit. Please take note that the Midwest Engine 398188 Needle & Seat Kit only comes with the needle and seat. If you also need a genuine Midwest Engine float replacement, you will need to purchase it separately.
