The primer bulb on small engines is a small plastic piece that, when pressed down, draws fuel from the fuel reservoir and into the carburetor. The carburetor is a part of the engine that mixes fuel and air together to make a combustion. Most small engines will not start if the carburetor is dry. Primer bulb won't fill with gas when pressed. I hear a little squeak. Engine won't start. Blower is only a year old. Bulb is not cracked or broken. I cleaned the carb, but still doesn't work. Mechanic's Assistant: I'll do all I can to help.
