Trimmer Purge Bulb 530058709

This part includes one purge bulb, also known as a primer bulb. It is supplied by the manufacturer to be a direct replacement for the original. The purge bulb is pressed, and this removes the air from the carburetor and supplies fuel into it. Without a functioning purge bulb, the user must pull the starter rope numerous times. Due to its rubber material and exposure to fuel, it has tendency to deteriorate over time, and can crack. A cracked purge bulb will make starting the engine very difficult. Before you begin this repair be sure to drain all the fuel from the tank. You will then remove the air filter cover, air filter, air filter base and the carburetor. Take note of the fuel lines and then remove them. Remove the metal plate that secures the primer bulb. Now do the same steps in reverse to install your new part.
