1. Remove the Spark Plug

The first thing you need to do is remove the spark plug. This will prevent the engine from starting while you work on fixing the flooding issue. Follow these steps:

  1. Locate the spark plug wire.
  2. Using a spark plug wrench, unscrew the plug from the engine.
  3. Inspect the spark plug for any signs of damage or wear. Replace it if necessary.

2. Clear Excess Fuel

To clear excess fuel from the engine, perform the following steps:

  1. Tilt the lawn mower with the air filter side up to prevent oil from spilling or contaminating the air filter.
  2. Using a clean cloth or paper towel, remove any excess fuel around the spark plug hole.
  3. Leave the spark plug out and let the engine sit for 10-15 minutes to allow the excess fuel to evaporate.

3. Clean or Replace the Air Filter

While waiting for the excess fuel to evaporate, check the air filter. If it’s dirty or clogged, cleaning or replacing it can improve engine performance. Here’s how:

  1. Locate the air filter housing on the lawn mower.
  2. Remove the cover or housing to access the air filter.
  3. If the filter is made of foam, wash it with warm, soapy water and let it dry completely. If it’s a paper filter, replace it with a new one.

The carburetor is often the culprit behind a flooded lawn mower engine. Follow these steps to inspect and clean it:

  2. Detach the carburetor bowl by removing the screws or clips that hold it in place.
  3. Carefully inspect the bowl for any signs of dirt, debris, or fuel residue.
  4. If you notice any clogs or blockages, clean the bowl using carburetor cleaner and a small brush.
  5. Reassemble the carburetor, ensuring all connections are secure.

5. Reinstall the Spark Plug and Start the Engine

Once you’ve completed the previous steps, it’s time to reinsert the spark plug and start the engine:

  1. Insert the spark plug back into the engine and tighten it with a spark plug wrench.
  2. Reconnect the spark plug wire.
  3. Set the lawn mower to the appropriate starting position (follow the manufacturer’s instructions).
