Understanding the Primer Bulb
The primer bulb is a small, often rubber component that plays a crucial role in starting two-stroke engines. By manually pressing the bulb, users can purge air from the fuel system, allowing for a smooth flow of fuel to the carburetor. This function is essential, especially after the equipment has been sitting idle.
How the Primer Bulb Works
The operation of the primer bulb is straightforward. When pressed, it creates a vacuum that pulls fuel from the tank into the fuel line and carburetor. This action fills the system with fuel and eliminates any trapped air, which could prevent the engine from starting or running smoothly.
