Parts for Briggs & Stratton 122T02-0153-B1: Carburetor, Engine, Valve Kits, Electric Starter Parts

This oil seal is a common part engineered to work in engines that power generators, vacuum cleaners, snowblowers, leaf blowers, mowers, and other small engine applications. The seal sits between the crankcase and the crankshaft. It is designed as a barrier to prevent oil leakage and to stop contaminants from leaving the crankcase. When the gasoline engine exhibits diminished power, and especially if it begins to emit oily gray or bluish smoke, there is a good chance the oil seal needs to be replaced. In order to replace the faulty seal, begin by removing the starter housing and taking off the nut that holds the starter wheel to the main shaft. The user will find the old seal on this shaft. Remove it and install the new seal, pushing it into place with the edges of a socket, then tapping it securely into place with a hammer. When choosing a replacement seal, remember to use an OEM genuine replacement part that is guaranteed to match the specs for the original part. This will ensure a quality match and long replacement life. This seal is compatible with Toro, Lawn-Boy, and Briggs & Stratton engines.

This genuine OEM gasket sits between the carburetor and cylinder to create a seal on a wide range of different lawn mower engines. The carburetor is responsible for mixing fuel and air, so it is important that it remains well sealed. The cylinder sits on top of the combustion chamber, and must also be sealed to provide the proper amount of pressure to drive the pistons. Therefore, it's crucial that nothing escapes from the engine where these two parts meet. Gaskets are designed to take a lot of wear and tear, but they can eventually blow after repeated exposure to heat and pressure. When a carburetor and cylinder gasket blows, the engine will not perform as well. Look out for vibrations, backfiring, low output, or an engine that stops shortly after startup. To replace this gasket, use a screwdriver, wrench set, and pliers to gain access to the carburetor's inner workings. This part is compatible with Toro, Lawn Boy, and Briggs & Stratton lawn mowers and comes sourced from its original manufacturer. This part ships individually.

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.
