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.

REMOVE COMBUSTION DEPOSITS: After every 100 hours of properly, remove the engine cylinder head. Scrape and wire brush the combustion deposits from the cylinder, cylinder head, top of the piston, and 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).
