Step 2: Remove The Spark Plugs

Next, remove the spark plugs from the engine. This will allow any excess fuel to evaporate and air to circulate, helping to clear the flood.

Step 3: Turn The Engine Over

Once the spark plugs are removed, turn the engine over a few times using the starter motor or a hand crank. This will help to expel any excess fuel that may be causing the flood.

Step 4: Clean The Spark Plugs

While the spark plugs are removed, take the opportunity to clean them using a wire brush or sandpaper. This will ensure that they are in good condition and will ignite properly when you replace them.

Step 5: Replace The Spark Plugs

After cleaning the spark plugs, replace them in the engine and tighten them securely. Be sure to connect the spark plug wires in the correct order, as mixing them up can cause further problems.

Step 6: Start The Engine

With the spark plugs replaced, attempt to start the engine again. If the engine starts and runs smoothly, then the flood has been cleared and you can continue driving as normal.
