Primer Bulb 188-12-1

This is a genuine OEM replacement part sourced directly from Walbro. When you press the primer bulb, it forces the air out of the carburetor. As the air leaves the carburetor fresh fuel will be pumped from the tank, through the fuel line, into the carburetor. This makes it easier to start the small engine in your outdoor power equipment. This primer bulb is commonly used in edgers, leaf blowers, trimmers, pruners, and tillers. Due to constant exposure to fuel, the primer bulb will deteriorate over time; it may lose elasticity or crack, it will then need to be replaced. The primer bulb is easy to access and replace, you will need a screwdriver to complete the job.
