Checking the Spark Plug

DO NOT check for spark with spark plug removed. DO NOT crank engine with
spark plug removed.
To ensure proper engine operation, the spark plug must be properly gapped and
free of deposits.
1. Remove the spark plug boot and use a spark plug wrench to remove the
plug.
If the engine has been running, the muffler will be very hot. Be careful not
to touch the muffler.
2. Visually inspect the spark plug. Discard the spark plug if there is apparent
wear, or if the insulator is cracked or chipped. Clean the spark plug with a
wire brush if it is to be reused.
3. Measure the plug gap with a feeler gauge. Correct as necessary by bending
side electrode. See Figure 15. The gap should be set to 0.024-0.031 in.
4. Check that the spark plug washer is in good condition and thread the spark
plug in by hand to prevent cross-threading.
5. After the spark plug is seated, tighten with a spark plug wrench to compress
the washer.
NOTE: When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer. When reinstalling a used spark plug,
tighten 1/8-1/4 turn after the spark plug seats to compress the washer.
IMPORTANT: The spark plug must be securely tightened. An improperly
tightened spark plug can become very hot and may damage the engine.
