Primer bulbs on small engines take the place of a choke on the carb . If your carb has a choke on it then you could probably bypass it . The object of the primer and the choke is to give the engine a extra charge of gas to help it start when the engine is cold . If you take this away then the engine will be hard starting if it starts at all .
Go to your local Small Engine Repair shop and ask for a gas cap with the primer pump on cap. They work great!
The primer on a lawnmower is a small bulb that helps to draw fuel into the carburetor, making it easier to start the engine. By pressing the primer, you inject a small amount of fuel into the engine, which provides the necessary mixture for ignition. This is especially useful for cold starts or when the mower has been sitting for a while. Essentially, it helps to ensure a quick and reliable start-up.
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.

The fuel line routing for a primer bulb typically involves connecting the fuel line from the fuel tank to one side of the primer bulb, and then connecting another fuel line from the other side of the primer bulb to the carburetor. The primer bulb acts as a manual pump that helps to draw fuel from the tank into the carburetor to aid in starting the engine. It is important to ensure that the fuel lines are properly connected and free of any kinks or blockages to ensure proper fuel flow.
