Identifying a faulty spark plug is essential for maintaining your generator’s performance. Look out for these common symptoms:

- Fuel consumption increases unexpectedly.
- Visible deposits, residue, or damage on the spark plug.

If deposits are present, carefully remove the spark plug, clean it with a small wire brush or knife, and verify that the gap is correctly set within the recommended range.
Step-by-Step Guide to Replacing Your Spark Plug

- Locate the spark plug by tracing the ignition wire connected to the engine.
- Disconnect the ignition wire by firmly twisting and pulling off the boot.
- Clean the area around the spark plug to prevent debris from entering the engine.
- Use the appropriate spark plug socket and ratchet to gently remove the old plug.
- Inspect the new spark plug for compatibility, correct model, and proper gap setting.
- Insert the new spark plug into the socket, tighten it carefully without over-tightening, and reconnect the ignition wire.
Following these steps ensures your Yamaha generator operates efficiently and reliably.
