Steps to Change the Spark Plug
- Ensure Safety: Make sure the engine is cool to the touch to avoid burns. Turn off the ignition and remove the key.
- Locate the Spark Plug: The spark plug is located on the right side of the engine. You may need to remove the seat or side panel for better access.
- Remove the Spark Plug Cap: Gently pull the spark plug cap off the spark plug. Be careful not to damage the cap or the wire.
- Remove the Old Spark Plug: Use the spark plug socket wrench to unscrew the old spark plug. Turn counterclockwise until it is loose enough to remove by hand.
- Check the Gap on the New Spark Plug: Use a gapping tool to ensure the new spark plug is gapped correctly. The recommended gap for the PW80 is 0.6-0.7 mm.
- Install the New Spark Plug: Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up. Do not over-tighten.
- Reattach the Spark Plug Cap: Push the spark plug cap back onto the new spark plug until it clicks into place.
- Test the Engine: Start the engine to ensure it runs smoothly. If it doesn't start or runs poorly, double-check the spark plug installation.
