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.

A carburetor on a lawn or garden appliance often has a float-feed chamber or bowl mounted on one side. This is a miniature fuel tank that takes a trickle feed from the main fuel supply. A carburetor is unable to use fuel that is under pressure, so the float chamber keeps everything at atmospheric pressure. When any sort of dirt or debris enters the fuel and air passages, it can cause an array of issues. The debris may enter due to shrinkage of O-rings and gaskets, and that is why a replacement gasket is essential. A carburetor screwdriver is essential when making this repair. Replacing it involves removing several pieces of the carburetor assembly, including a float assembly, inlet needle valve, and the old fuel bowl gasket itself. This authentic replacement carburetor bowl gasket will fit a small engine carburetor bowl on wood chippers, leaf blowers, pressure washers, tillers, snowblowers, lawnmowers, and small engines. It is compatible with Briggs & Stratton, Toro, Simplicity, Lawn-Boy, Cub Cadet, and Snapper, among others.

This replacement exhaust gasket is an authentic OEM part for a snowblower or lawn tractor engine. On these appliances, the exhaust is located quite near to the air filter, meaning that there is a chance that exhaust could leak into the carburetor. The carburetor requires fresh air to oxygenate fuel for combustion, so manufacturers install a gasket to help seal off the exhaust. Once installed, gaskets exist under a lot of pressure and will absorb the heat of the engine. These stresses cause gaskets to slowly degrade and eventually break their seal. If the exhaust gasket blows, the engine will not perform as it should. Be cautious of a noisy engine that burns more fuel than usual and gives off a burning smell. These are signs that the exhaust gasket has given out. If so, use a socket wrench and wrench set to disassemble the blower and air filter housings, then remove the exhaust manifold and change out the broken gasket. This high-quality replacement exhaust gasket is compatible with engines made by Toro, Husqvarna, Briggs & Stratton, and Snapper. It comes sourced from the original manufacturer and ships individually.

This exhaust gasket is a genuine Midwest Engine replacement part for appliances that use small engines, such as chipper shredders, snowblowers, leaf blowers, and lawn mowers. The function of an exhaust gasket is to seal off the carburetor from the exhaust tube in order to protect the engine from the accumulation of dirt, debris, and gunk within the inner workings. The exhaust gasket may require replacement over time from general wear and tear. If the exhaust gasket is not sealing, allowing dirt and debris to accumulate within the carburetor and leaving the exhaust tube exposed, the part should be replaced immediately. Evidence of a damaged exhaust gasket could also manifest in the form of oil leakage, black smoke arising out of the exhaust tube, and unusually low pressure from the combustion when using the appliance. Any of these symptoms can be attributable to multiple factors, so one should assess if the exhaust gasket is responsible before ordering a replacement.This exhaust gasket is compatible with the following brands: Briggs and Stratton, Cub Cadet, Toro, and Simplicity.
