Final Adjustment—Turn needle valve in until
engine misses (lean mixture). Then turn it out past
smooth operating point until engine runs eneven-
ly (rich mixture). Now turn needle valve to the mid¬
point between rich and lean so the engine runs
smoothly. Hold throttle at idle position and set
idle speed adjusting screw until fast idle is ob¬
tained (1750 RPM). Hold throttle in idle position
and turn idle valve in (lean) and out (rich) until
engine idles smoothly. Then reset idle speed ad¬
justing screw so that engine idles at 1750 RPM.
Release throttle—engine should accelerate
without hesitation or sputtering. If engine does
not accelerate properly, the carburetor should be
readjusted to a slightly richer mixture.
ADJUSTING CARBURETOR CHOKE
Proper choke adjustment is dependent upon prop¬
er adjustment of remote controls on the powered
equipment.
To Check Operation of Choke-A-Matic Controls:
Move control lever to "CHOKE" position. See
figure 10. The carburetor choke should be closed.
NOTE
The air cleaner can be removed to
check the operation of the choke.
To Adjust:
Place control lever on equipment in FAST (high
speed) position. Loosen control casing clamp
screw B. Move control casing A and wire until
lever D touches choke operating link at C. Tighten
casing clamp screw B. See figure 24.
