CLEANING AND GAPPING SPARK PLUG
1. Remove and inspect spark plug. If porcelain is
cracked or electrodes are pitted, install a new
spark plug.
IMPORTANT: DO NOT CLEAN SPARK
PLUG IN A MACHINE USING ABRASIVES.
2. If spark plug is in good condition, clean plug by scraping or using a wire brush.
Wash with a commercial solvent.
3. Use a round wire-type feeler gauge to check for a gap of 0.70 to 0.80 mm (0.028 to
0.031 inches.)
