does need adjustment, proceed as follows: In general, tuming the adjusting needles in (clockwise) decreases the supply of fuel to the engine giving a leaner fueVair mixture.

Tuming the adjustingneedles out (counter- clsekwise) increases the supply of fuel to the

engine giving a ricber fueVair mixture. IMPORTANT: Damage to the needles and

seats in carburetor may result if turned in too tight.

engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous, If you think the engine-governed high speed needs adjusting, contact a Sears or other
