A gas primer bulb on a Lawn Boy lawnmower engine works by creating a vacuum that draws fuel from the tank into the carburetor, ensuring that the engine has the necessary fuel to start. When the bulb is pressed, it forces air out and pulls in a small amount of fuel, priming the system. Once released, the bulb refills with fuel, and this process helps eliminate air in the fuel lines, facilitating easier starts, especially after the mower has been sitting for a while. This simple mechanism enhances the reliability of the engine's ignition process.
