Description

This genuine OEM primer bulb and valve repair kit is an identical replacement for certain models of lawn mower engines. The primer bulb is pressed prior to cold starting the engine, usually three times, which sends fuel into the carburetor. This helps the carburetor start more effectively and ensures smoother operation. The primer bulb assembly is exposed to the elements and it is a part that sees a lot of repetitive motion. As a result, it can wear out, become brittle and crack, or experience other failures. In some instances, the primer bulb and valve may be lost in the process of other repairs. Replacing it with a genuine part like this will provide an exact fit. This OEM primer bulb and valve repair kit is manufactured by Tecumseh and is compatible with several of its engines, as well as some engines found in Toro lawn mowers. There are about 20 machines that take this part, which is a complete kit for the primer and valve. The replacement kit includes the primer bulb, seal, plastic valve, and metal spring. It is important to allow the engine to cool completely before replacing this or any other parts. Wear gloves for hand protection.
