This screw is a genuine Midwest Engine replacement part for small engine appliances, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. The purpose of a screw is to tightly link materials together through rotation that pierces into the material. A screw might have to be replaced in the event that it is lost or misplaced, a common occurrence due to its size. A screw might also be replaced if it deteriorates over time, through erosion, cracking, or piercing, thereby reducing its efficacy in holding materials together. This kind of damage can be attributed to general overuse, to age, or simply to long-term exposure. If a screw is subject to any of this kind of damage, it is best to replace it immediately, as the materials held together by the screw must continue to be held together. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This screw is compatible with the following brands: Briggs & Stratton, Toro, Cub Cadet, and Lawn Boy.

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.

Seals the carburetor from the exhaust tube to protect your engine. Replace if you notice exhaust leaks or decreased performance. Confirm fit with your model.
