Prime the Engine: Start the mower, let it run for a few minutes, and then stop

To prime the engine of your lawn mower and ensure it runs smoothly, follow these steps:

Start by turning on the mower and allowing it to run for a few minutes. This initial running period is crucial as it helps to prime the carburetor and ensure the engine receives a fresh fuel-air mixture. During this time, the engine will begin to warm up, and the carburetor will start to prime itself. You'll notice the mower's engine will start to sound more stable and less 'starved' for fuel.

After a few minutes, carefully shut off the engine. This action is an essential step in the priming process. When you turn the engine off, the carburetor continues to draw fuel into the system, creating a small amount of vacuum. This vacuum helps to draw air into the carburetor, ensuring that the engine has a steady supply of fresh air when you restart it.

Now, let the mower sit for a short while, typically around 5-10 minutes. This waiting period allows the carburetor to continue the priming process and ensures that any residual fuel in the system is burned off. It's important not to rush this step, as it directly impacts the engine's performance.

Finally, restart the mower and let it run for a while. You should notice an improvement in the engine's performance and a reduction in any previous issues with starting or running. This method of priming the engine is a simple yet effective way to ensure your lawn mower operates efficiently, especially after periods of disuse or when dealing with clogged fuel lines.
