SPARK PLUG
• Starting failure and misfiring are often caused by a
fouled spark plug. Clean the spark plug and check
that the plug gap is in the correct range. For a re-
placement plug, use the correct type specified by
ZENOAH.

• REPLACEMENT PLUG IS A NGK CMR7H.
IMPORTANT
• Note that using any spark plug other than those des-
ignated may result in the engine failing to operate prop-
erly or in the engine becoming overheated and dam-
aged.
• To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
