Step 8: Replace the spark plug.
Purchase a replacement spark plug that is identical to the old one. Using a spark plug feeler gauge, set the gap of the spark plug to the manufacturer's recommended setting. First, thread the spark plug into the cylinder by hand to prevent cross-threading, then tighten with a ratchet and socket. Finish with a 1/2 turn after the spark plug seats to compress the washer.
