TO ADJUST CHOKE CONTROL
The choke control has been preset at the factory and adjustment should not be necessary, check adjustment as de- scdbed below before loosening cable, If
adjustment is necessary, proceed as follows:
1, With engine not running, move choke control (located on dash panel) to full choke position.
2.Remove air cleaner cover, filter and cartddge plate to expose carburetor choke (See =AIR FILTER" in the
Maintenance section of this manual),
3.Choke should be closed. If it is nat, loosen casing clamp screw and move choke cable until choke is completely closed. Tighten casing clamp screw securely.
4.Reassemble air cleaner,

TO ADJUST CARBURETOR
The carburetor has been present at the factory and adjustment should not be necessary. However, minor adjustment may be required to compensate for differences in fuel, temperature, altitude or load. If the carburetor does need adjustment, proceed as follows:
In general, fuming the adjusting needles in (clockwise) decreases the supply of fuel to the engine giving a leaner fuel/air mixture. Turning the adjusting needles out (counterclockwise) increases the supply of fuel to the engine giving a richer fuel/ air mixture.
1.Be sure you have a clean air filter, and
the throttle control cable is adjusted propedy (see =TO ADJUST
THROTTLE CONTROL CABLE" in the Service and Adjustments section of this manual).
2.With engine off turn idle fuel adjusting needle in (clockwise) closing it finger tight and then turn out (counterclock- wise) 1 turn.
FINAL SETTING -
1.Start engine and allow to warm for five minutes. Make final adjustments with engine running and shiflJmotion control lever in neutral (N) position.
NOTE: The high idle is set at the factory and cannot be adjusted.
2.Idle seeed setting - With throttle control lever in slow position,engine should idle at 1200 RPM. If engine idles too slow or fast, tum idle speed adjusting screw in or out until correct idle is attained.
3.Idle fuel needle setting - With throttle control lever in slow position, turn idle fuel adjusting needle In (clockwise) until engine speed decreases and then turn out (counterclockwise) approximately 3/4 turn to obtain the best low speed performance.
4.Recheck idle speed. Readjust if necessary.
ACCELERATION TEST -
5. Move throttle control lever from slow to
fast position. If engine hesitates or dies, turn idle fuel adjusting needle out (counterclockwise) 1/8 turn. Repeat test and continueto adjust, if necessary, until engine accelerates smoothly.
High speed stop is factory adjusted. Do

engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed settingcan be dangerous. If you think the
