How do you get out a Spark plug in lawn mower that is stuck?

1. Detach the Spark Plug Wire:

- Disconnect the spark plug wire from the spark plug by pulling straight up on the connector. Avoid pulling on the wire itself to prevent damaging it.

2. Locate the Spark Plug:

- Identify the spark plug location, which is usually on top of the engine or on the side of the cylinder head.

3. Apply Penetrating Oil:

- Apply a penetrating lubricant like WD-40 to the spark plug threads.

- Allow it to soak for several minutes to help loosen the stuck threads.

4. Use a Spark Plug Socket:

- Attach a deep socket wrench or spark plug socket onto the spark plug. Make sure the socket fits securely to avoid slipping.

5. Loosen the Spark Plug:

- Turn the wrench counterclockwise to loosen the spark plug.

Apply gentle force initially, and gradually increase it if needed.

6. Remove the Spark Plug:

- Continue turning the wrench until the spark plug loosens and comes out of the cylinder head.

7. Inspect the Spark Plug:

- Once removed, inspect the spark plug for any signs of damage, such as worn-out electrodes, dirty threads, or cracks.

8. Reinstall the Spark Plug:

- If necessary, clean the threads or reinstall a new spark plug. Make sure to set the correct gap before reinstalling the spark plug.

9. Tighten the Spark Plug:

- Hand-tighten the spark plug until it's snug.

- Use the wrench to give it an additional 1/4 to 1/2 turn. Avoid over-tightening to prevent damaging the threads.

10. Reattach the Spark Plug Wire:

- Reattach the spark plug wire by pushing down on the connector until it snaps back into place.

- Ensure that the connection is secure to avoid any spark leakage.

11. Test the Lawn Mower:

- After reinstalling the spark plug, start the lawn mower to check if it runs properly.

Note: If the spark plug is extremely stuck and none of the above methods work, you may need to seek professional help from a small engine repair shop.
