It is compatible with lawn mower engines in models from Briggs & Stratton and Toro, and will fit on over 150 different engine models in lawn mowers from these brands.

This is a carburetor overhaul kit that is compatible with over 150 different small gasoline-powered tools. This equipment includes leaf blowers, power vacuums, lawn mowers, and other small engine tools. Each of these engines employs a carburetor where the air and fuel come together to be mixed before flowing into the combustion chamber to be ignited. Since the carburetor is where the raw products of air and gasoline come together, is it especially susceptible to air and fuel impurities. Particulate matter that escapes air filtration and contaminants in the gasoline eat away the gaskets that seal the entrances and exits to the carburetor. Eventually, users may notice that the power tool starts up but has little power and quickly dies. This is often a sign of a fouled carburetor. This kit, which is an OEM certified genuine replacement part that perfectly replicates the original, has all 16 pieces necessary to rebuild the carburetor so it works exactly as it did when new. Because a carburetor overhaul is one of the more detailed repairs a user may perform, it is a good idea to refer to the owner's manual for a diagram showing the proper order of components. This kit is compatible with Toro and Briggs & Stratton.

This genuine Midwest Engine carburetor mixes fuel and air and directs the flow of that mixture into the fuel lines through which the spark plugs are ignited and the lawnmower engine is started.The carburetor of a lawnmower might have to be replaced if it has suffered damage such that it can no longer perform its function, which can result in a stalled or misfiring engine, an engine that will not turn on, or oil leaking directly from it. To test if the problem is the carburetor, pour a tablespoon of oil directly into the carburetor, ignite the engine, and see if the engine starts. If it does not start or it stalls, the carburetor should be immediately removed and replaced. The appliance cannot be used until it has been replaced by this genuine OEM part. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This carburetor is compatible with the following brands: Midwest Engine, Briggs & Stratton, Toro, and Cub Cadet. This part is sold individually.

The carburetor float is housed in the carburetor and is used to help control the fuel flow. It adjusts the needle valve and ensures that the appropriate amount of fuel reaches the carburetor bowl. This helps provide the right mixture of air and gasoline for the engine to operate at optimal performance. Over time, the float can become worn or detached, or the pin could come loose. When this happens, the flow is affected, and the engine will not operate correctly. If the float isn't working correctly on a lawnmower or another small engine, it might be time for a replacement. This replacement part is a genuine OEM product designed to be used with many Briggs & Stratton engines, including lawnmowers, pressure washers, generators, and other lawn and outdoor equipment engines. It is sold as a single unit with the metal cotter pin included. There are more than 150 compatible machines that this unit will work with. If your lawnmower isn’t working as it should or if the float has come loose and can't control the flow appropriately, this OEM replacement can get things back in working order.

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.

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 is a genuine OEM air cleaner gasket replacement sourced directly from the manufacturer. This gasket provides the seal between the carburetor and air filter on various lawn and garden engines. The seal is essential to engine performance. If dirty air or too much air gets into the carburetor, the ratio of fuel to air will be off and the engine may misfire, not run at all, or die during operation. Normal use of outdoor machinery will produce wear and tear on the air cleaner gasket that cannot be seen during operation. It isn't until the engine runs badly that the worn gasket is discovered. This is remedied by including the air cleaner gasket in regularly scheduled maintenance. Before changing the air cleaner gasket, make sure the engine is cool. Severe burns can happen if the engine is still hot. Wear gloves while making repairs as an added layer of protection. Remove the air cleaner cover and air filter to access the gasket. Remove the gasket and clean behind the gasket. Install the new gasket, making sure the part is flat. Reinstall the air filter and cover. This air cleaner gasket is sold individually. This gasket is compatible with small engines manufactured by Briggs & Stratton and Cub Cadet.

The choke return spring is a part that is used on many small engines in lawn and garden equipment. The part is a component in the choke system that ensures that the correct tension is applied to keep the choke lever in the appropriate position. If the choke return spring is broken or begins to malfunction, the lawnmower may have issues keeping power and running correctly.If the choke return spring is damaged or weak, it will prevent the choke from returning to the correct position. This can cause the engine to speed up and accelerate more quickly than desired. The air filter housing will need to be unscrewed to access the choke return spring. Take the wire off the spark plug and remove the boot from the plug. Remove the spring from the linkage and then clip on the new one. Replace the other components to get the equipment to work again.This choke return spring is an authentic OEM replacement part directly sourced from the manufacturer. It is sold individually. The spring is compatible with various wood chippers, lawnmowers, and pressure washers by Briggs and Stratton, Simplicity, Toro, Lawn-Boy, and Cub Cadet.
