If the engine has been running, the muffler will be very hot. Be careful
not to touch the muffler.
NOTE: Check the spark plug once a season or every 25 hours of
operation. Change the spark plug once a season or every 100 hours.
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. See Figure 20.
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 21. The gap should be set
to .02-.03 inches (0.60-0.80 mm).
