As a mechanic, I want to share a comprehensive and easy-to-follow guide to help you start your lawn mower with old gas and ensure that your machine remains in proper working condition. Please adhere to the safety precautions and use the necessary tools while handling the device.

Here are some simple steps for the lawnmower old gas starting procedure.

1. Detaching the Spark Plug

1. Locate your lawn mower’s spark plug. Check the consumer manual if you are unsure about its location.
2. Using your hands or a wrench, gently remove the spark plug wire from the plug by pulling on the boot.

2. Removing Oil and Old Gas

1. Use a flathead screwdriver to open the gas cap and place the funnel inside the gas tank.
2. Place the gas container under the funnel and slowly tip the lawn mower to pour the old gas into the container. Be careful not to spill the old gas on the engine or the ground.
3. For the oil, locate the oil drain plug according to your lawn mower’s user manual and use a wrench to remove it. Place an oil container under the drain plug to catch the old oil.
4. Following local regulations, allow all the old oil to drain and properly dispose of it.

3. Cleaning or Replacing the Spark Plug

1. Check the spark plug for any signs of wear, corrosion, or carbon buildup. If it looks dirty, use an old rag to clean it off. If any of these issues are severe, consider replacing the spark plug.

4. Priming the Engine (if applicable)

1. Locate the primer bulb of your lawn mower, which is generally a small rubber button near the carburetor.
2. Press the primer bulb a few times to send fresh fuel to the carburetor.

5. Filling Up With Fresh Gas and Oil

1. Pour fresh gas into the lawn mower’s gas tank using a funnel, but do not overfill it. Close the gas cap when done.

6. Starting the Engine

1. Reassemble the spark plug wire to the spark plug.
2. Start the lawn mower following the standard procedure– pulling the start cord or turning the key.
