Spark Plug Service

In order to service the spark plug, you will need a spark plug wrench (commercially available).

Recommended spark pl

ugs: NHSP LD F7TC or NGKBPRGES but we recommend our OEM spark

plug. To ensure proper engine operation, the spark pl

ug must be properly gapped and free of

deposits.

1. Remove the spark pl

ug cap.

2. Use a spark pl

ug wrench to remove the spark plug.

3. Visually inspect the spark pl

ug. Discard it if the insulator is cracked or chipped. Clean the spark

ug with a wire brush if it is to be reused.

4. Measure the pl

ug gap with a feeler gauge.

5. Check that the spark pl

ug washer is in good condition.

6. After the spark pl

ug is seated, tighten with a spark plug in by hand to prevent cross-threading.

7, After the spark pl

ug is seated, tighten with a spark plug wrench to compress the washer.

NOTE: THE SPARK PLUG MUST BE SECURELY TIGHTENED. AN IMPROPERLY

TIGHTENED SPARK PLUG CAN BECOME VERY HOT AND COULD DAMAGE THE

ENGINE. NEVER USE SPARK PLUGS WHICH HAVE AN IMPROPER HEAT RANGE.

USE ONLY RECOMMENDED SPARK PLUS OR EQUIVALENT.
