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.

fast, tum idle speed adjusting screw in or out until correct idle is attained.

4.Idlefuel needle setting - With throttle control lever in slow position,turn idle fuel adjustment needle in (clockwise) until engine beginsto die and then tum out (counterclockwise)until engine runs rough. Turn needle to a point midway between those two positions.

engine accelerates smoothly.

High speed stop is factory adjusted. Do not adjust - damage may result. IMPORTANT= Never tamper with the

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
