The filter pre-cleaner is a first-stage cleaning system for the air filter in combustion engines. Typically, a pre-cleaner will be made of a dense foam material and will fit around a cartridge-style air filter, adding an extra level of filtration for any air coming into the engine. Over time, both the pre-cleaner and the filter can become clogged with regular use and typically need to be replaced as part of routine maintenance. However, intermittent clogs and damage can also occur that would necessitate an emergency replacement. Many people keep an extra set on hand in case of urgent repair needs. This genuine OEM filter pre-cleaner is specifically designed to fit select Briggs & Stratton engine air filters. It is compatible with over 150 machines from the brand, as well as select Toro machines that feature Briggs & Stratton engines.

This is a replacement fuel tank gasket. It installs between the carburetor and the fuel tank assembly, and is sometimes called a carburetor gasket or a fuel tank assembly gasket. It helps to prevent leaks from occurring between the fuel tank assembly and the carburetor. Gaskets are subject to high temperatures and pressure. Over time, they will degrade, and leaks will eventually occur. When this happens, the gasket must be replaced. The gasket should also be replaced whenever the fuel tank assembly/carburetor are separated, such as to repair or replace the carburetor float. Signs the gasket needs to be replaced include visible leaks between the carburetor and the fuel tank and operational problems with the machine. To replace the fuel tank gasket, remove the air box and air filter. Disconnect the spark plug, and then crimp the fuel line closed. Remove the carburetor and then remove the old gasket. Note that it may require scraping. Make sure that both mating surfaces are clean and dry before installing the new gasket. Reassemble everything in reverse order.

This genuine Midwest Engine foam pre-cleaner can be used as a replacement part for appliances operated by small engines, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. A foam pre-cleaner is an air filtration system made of a foam layer through which the air must pass before accessing the primary air filter. The purpose of a foam pre-cleaner is to put less stress and strain on the primary air filter, thereby requiring fewer primary air filter changes. The foam pre-cleaner in a small engine appliance should be cleaned once every 24 hours of appliance usage; if it is not cleaned regularly on this timetable, it is highly likely that it will have to be replaced after less than optimum hours of appliance usage. If the regular air filter has to be changed more than usual, it is likely that the current foam pre-cleaner has to be replaced as well. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This foam pre-cleaner is compatible with the following brands: Midwest Engine, Briggs & Stratton, Toro, and Simplicity.

The largest factor hampering the engine efficiency of lawn mowers is the air in the air/fuel mix. This Briggs & Stratton pre-cleaner filter is a flat device that sits inside the air filter housing and purifies the air of contaminants and particulates before it even reaches the air filter. This improves the lifespan of the air filter and improves the efficiency of the engine. The pre-cleaner, because it is highly effective at removing dust and other contaminants from the air, will eventually become full of particulate. At that point, the user may notice difficulty in getting the mower to perform. To replace the pre-cleaner, remove the outer air filter cover snd locate the old pre-cleaner just inside. Remove the old filter and replace it with the new one. Attach the top cover. This is an OEM certified replacement part that was built to the exacting standard of the original equipment of the tractor. Although it was manufactured intentionally for the Toro lawn tractor, the filter is also compatible with several other brands, including Simplicity and Briggs & Stratton.
