Caution
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug before you do
any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
