If your engine is having trouble starting, you may be in need a new purge bulb. When the engine has been sitting for a while, unused, the fuel will drain and eventually dissolve out of the carburetor. The next time you go to use your equipment, the engine will not start until the carburetor has fuel in it. The purge bulb, also commonly referred to as a primer bulb, manually pumps fuel back into the carburetor, while purging air out. If the purge bulb is malfunctioning, you will need to pull the starter rope numerous times until the carburetor diaphragm can pump the right amount of fuel back into carburetor for the engine to start. This purge bulb is prone to hardening and cracking over time because it is in continuous contact with fuel and will need to be replaced. This part is sourced directly from the manufacturer and sold individually.
