CLEAN OR REPLACE SPARK PLUG: Clean or
replace the spark plug after every 100 hours of opera-
tion or every season, whichever comes first. Do not
blast the spark plug clean with an abrasive cleaning
device. Clean the plug by scraping it or by using a
wire brush. Wash the plug with a commercial solvent.
After cleaning or when installing a new spark plug, set
the terminal gap to .030 inch (.76 mm) with a feeler
gauge. See Figure D.5.

around the valves. Refit the gasket (replace it if dam-
aged) and reassemble the cylinder head and block.
Turn down the screws finger tight. Torque the screws
in a staggered sequence to 165 inch-pounds (19 N·m).
