Preparing Your Lawn Mower for Starting

Before you even think about starting your lawn mower, it’s important to give it a quick check-up. This will ensure everything is in working order and prevent any unexpected problems.

1. Fuel Level

The first step is to check the fuel level. Most lawnmowers have a translucent fuel tank, making it easy to see how much fuel is left.

  • If the tank is empty: Refuel your mower with fresh, high-quality gasoline. Avoid using old or stale fuel, as it can gum up the carburetor and cause starting problems.
  • If the tank is full: You’re good to go!

2. Oil Level

Next, check the oil level. Your lawn mower’s engine needs oil to lubricate its internal parts and prevent them from overheating.

  • Locate the dipstick: The dipstick is usually located on the side of the engine.
  • Wipe the dipstick: Use a clean cloth to wipe the dipstick clean before inserting it back into the engine.
  • Check the oil level: Once the dipstick is fully inserted, pull it out and check the oil level. It should be between the “full” and “low” marks.
  • Add oil if necessary: If the oil level is low, add more oil until it reaches the “full” mark. Use the type of oil recommended by the lawn mower manufacturer.

3. Spark Plug

The spark plug is responsible for igniting the fuel-air mixture in the engine. A worn or fouled spark plug can prevent your mower from starting or running smoothly.

  • Locate the spark plug: The spark plug is usually located on the top of the engine, beneath a metal cover.
  • Remove the spark plug: Use a spark plug wrench to loosen and remove the spark plug.
  • Inspect the spark plug: Check the spark plug for wear and tear, such as cracks, corrosion, or excessive carbon buildup.
  • Replace the spark plug if necessary: If the spark plug is damaged or worn, replace it with a new one that matches the specifications in your lawn mower’s manual.

2. Choke Settings

The choke restricts airflow to the engine, helping it to start in cold conditions.

  • Check the choke setting: Most lawn mowers have a choke lever or button. Locate it and check the setting.
  • Engage the choke if needed: If the engine is cold, engage the choke. You’ll know it’s engaged when the lever is in the “choke” position or the button is pressed in.

3. Start the Engine

Now, it’s time to fire up the engine!

  • Pull the recoil starter cord: For most lawn mowers, you’ll need to pull a cord to start the engine. Grasp the cord firmly, pull it out quickly and firmly, and then let it go. The recoil starter will wind up, and then spring back, turning the engine over.
  • Turn the ignition key: Some lawn mowers have an ignition key. Turn the key to the “start” position.

4. Disengage the Choke

Once the engine starts and idles smoothly, you can disengage the choke.

  • Check the choke setting: Locate the choke lever or button and check its position.
  • Disengage the choke: Slowly release the choke lever or button. You may need to adjust the throttle slightly to keep the engine running.

Troubleshooting Common Starting Problems

Even with careful preparation, you may encounter problems starting your lawn mower. Here are some common starting issues and how to troubleshoot them:
