This is a genuine Walbro replacement part. The primer check valve is found underneath the primer bulb; it helps the fuel to flow in one direction, and allows the primer bulb to fill with fuel. Due to constant contact with fuel the check valve can deteriorate over time. If the check valve starts to break apart, or gets clogged the fuel will not flow into the carburetor properly, the primer bulb won?t be effective, and the engine will be difficult to start, if it starts at all. The primer check valve should be replaced at the same time as the primer bulb.
