You should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
deposits with a wire or pin and adjust the
spark plug gap.
To access the spark plugs:
1) Remove the engine cover.
2) Disconnect the coupler (1) while push-
ing the release lever.
3) Remove the bolt.
4) Pull the ignition coil out.
