CHECKING THE SPARK PLUG
– Only use the supplied universal wrench to remove or to install the spark plug.
– The gap between the two electrodes of the spark plug should be 0.7 - 0.8 mm
(0.028" - 0.032"). If the gap is too wide or too narrow, adjust it. If the spark
plug is clogged or contaminated, clean it thoroughly or replace it.
Place the plug cap properly as illustrated after checking.
CAUTION: Never touch the spark plug connector while the engine is running
(danger of high voltage electric shock).
