This is a carburetor float that is used in a wide variety of lawn and garden equipment. The carburetor float is used in the engine to close and open the float needle valve. The main responsibility of the carburetor float is to open up to allow fuel into the carburetor when drained and to shut off the flow of fuel if the bowl is filled. If the float isn't working properly, the engine may not idle, the carburetor can flood, and the motor may stall while the tool is in use.Before replacing the carburetor float, put on work gloves and disconnect the spark plug wire. The carburetor will need to be removed from the equipment. The carburetor float and any other malfunctioning parts can be taken out and replaced with new components. While working on the parts, the jets can also be cleaned as a maintenance process.This carburetor float is sold as an individual item.

The floats themselves can be visually inspected for any signs of damage or wear and the float bowl gasket can be replaced if there are signs of either. If the operator can hear gas inside of the floats, then a new float bowl gasket will be needed.This is a genuine OEM part sourced directly from Midwest Engine. It is sold individually.

This replacement valve seal is a genuine OEM part for a lawn tractor or mower. The valve stem is a type of valve that transfers oil into the cylinder and then immediately reseals due to the pressure in the chamber. However, if the seal is damaged, it will not close and oil will leak into the cylinder. If this happens, the cylinder head may become overly lubricated and not run well. This seal helps prevent that from happening. It fastens to the intake valve and valve stem keeper. Seals will naturally wear out over time due to stress and exposure to corrosive oxidizing agents in an engine. When this happens, the valve will leak oil. To test if the valve seal is compromised, look for whitish-grey smoke that indicates burning oil and also measure to see how much oil the engine is consuming. If the seal is breached, use a screwdriver and socket wrench set to change out the part. This top of the line replacement valve seal is compatible with Briggs & Stratton, Toro, and Lawn Boy lawn tractors. It is sourced from the original manufacturer and ships individually.

This brush retainer is part of the starter motor on many types of lawn and garden machinery. It comes with both the retainer and a set of four brushes. The main job of the brush retainer is to hold a set of carbon brushes against the commutator bars located on the armature. If the brush retainer is worn, damaged, or improperly seated, it can cause problems with the equipment. The starter motor will not be able to get the proper amount of current from the battery.If the brush retainer might be causing problems, a visual inspection can be performed. A damaged brush retainer can wear down to the wire lead and become burned, pitted, or cracked. When the brush retainer is worn out, it can decrease engine performance, reduce braking, and cause the motor to lose power. This brush retainer is an authentic OEM replacement part sourced directly from the manufacturer. It is sold as an individual part. The retainer is made to be used with lawnmowers, snowblowers, tillers, and wood chippers created by Briggs & Stratton, Craftsman, Toro, Cub Cadet, Lawn-Boy, Snapper, MTD, and Simplicity.
