Step 1: Prepare Your Lawn Mower
Before you begin, turn off your lawn mower and disconnect the spark plug wire. This will ensure your safety while working on the mower. Locate the spark plug on your lawn mower, which is typically located near the engine.
Step 2: Remove the Old Spark Plug
Using a spark plug socket and wrench, carefully remove the old spark plug from the lawn mower. Be gentle when removing it to avoid damaging the surrounding components. You can also use a spark plug gap tool to check the gap between the electrodes.
Step 3: Choose the Right Spark Plug
It’s important to choose the right spark plug for your lawn mower. Check your manufacturer’s manual for the recommended type of spark plug, or consult with a lawn mower expert. Once you have the new spark plug, check the gap and adjust it as necessary.
Step 4: Install the New Spark Plug
Using a spark plug socket and wrench, carefully install the new spark plug in the same location as the old one. Tighten it gently, but not too tight, as this can cause damage to the threads.
Step 5: Reconnect the Spark Plug Wire
Once the new spark plug is installed, reconnect the spark plug wire. It’s important to make sure it’s securely connected, as a loose wire can cause problems with starting and running the lawn mower.
