Spark Plug Maintenance
In order to service the spark plug, you will need a spark plug wrench (commercially available).
Recommended spark plugs TORCH F6RTC but we recommend our OEM spark: plug.
To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug base.
3. Use a spark plug wrench to remove the spark plug.
4. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark
plug with a wire brush if it is to be reused.
5. Measure the plug gap with a feeler gauge.
(Correct as necessary by carefully bending the side
electrode.) The gap should be: 0.70-0.80 mm (0.028-0.031in)
6. Check that the spark plug washer is in good condition.
7. After the spark plug is seated, tighten with a spark plug in by hand to prevent cross-threading.
8. After the spark plug 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.
