Step-by-Step Instructions
1. Locate the Spark Plug
Identify the spark plug on your lawn mower. It’s usually located on top of the engine, near the cylinder head.
2. Disconnect the Spark Plug Wire
Use a screwdriver to gently pry the spark plug wire off the spark plug. Do not pull on the wire itself.
3. Grip the Spark Plug
Using an adjustable wrench or pliers, firmly grip the spark plug base. Ensure that it’s secure, but avoid over-tightening.
