When the fuel in a small, gasoline-powered engine moves up the fuel line, it must be mixed perfectly with air and together burn in just the right mixture and amount in order for engines to function properly. Because too much gas might be coming into the carburetor or because there might be a need for more gasoline than can readily move up the fuel line, the carburetor has a small device called the float bowl. The float bowl has a ready supply of gasoline for use as needed by the carburetor. To keep the gasoline in check while all this is happening, a device called the float bowl gasket keeps all the elements separate. With use and age, sometimes these gaskets crack or grow brittle and must be replaced. This causes air to leak into the mix and the engine will not operate smoothly. Replace this gasket with a genuine OEM replacement part like this one, manufactured to be exactly like the factory original that is being replaced. This part is compatible with engines sold by Toro, Simplicity, MTD, Briggs & Stratton, and Cub Cadet. Part sold individually.

This part is a float bowl gasket. It is manufactured for use on a variety of outdoor power equipment engines.

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 friction spring is a genuine OEM part meant for any number of small appliance engines run using a starter rope. This spring absorbs large amounts of kinetic energy that could damage the starter rope pulley system. It helps keep the pulley from being overstretched, which would create enough pressure to break the entire system. This spring sits at the center of the pulley system and creates resistance as the user yanks the starter rope. Friction springs can become worn out after repeated use, especially if a user tends to yank the starter rope quite forcefully. The most obvious sign of a worn of friction spring is if the pulley system lacks any resistance. As the user pulls the cord, they should feel a little pull back, but if the friction spring is worn, there will be much less resistance. Replacing this part is straightforward and will only require a screwdriver. Simply open the pulley system, carefully remove the old spring, and install the new one. This part is compatible with a wide number of appliances from Toro, Vanguard, Briggs & Stratton, and Lawnboy. It comes sourced from the original manufacturer and ships individually.
