CARBURETOR PRESETS
When making carburetor preset adjust­
ments, do not force plastic limiter caps
beyond stops or damage will occur.
If carburetor presets are not needed,
proceed to ADJUSTING PROCEDURE,
IDLE SPEED.
To adjust presets:
• Turn mixture screw counterclockwise
until it stops.
• Turn the idle speed screw clockwise
until it stops. Now turn counterclock­
wise 4-1/2 turns.
• Start motor, cut grass for 3 minutes,
and proceed to the adjustment
section, if engine does not start,
refer to troubleshooting chart or call
1-800-235-5878.
• If engine performance is acceptable
at the preset positions, no further
adjustment is necessary.
ADJUSTING PROCEDURE
Idle Speed
Allow engine to idle. Adjust speed until
engine runs without stalling.
• Turn clockwise to increase engine
speed if engine stalls or dies.
• Turn counterclockwise to decrease
speed.
No further adjustments are necessary
if performance is satisfactory.
Mixture Adjustment “H”
DO NOT operate engine at full throttle
for prolonged periods while making ad­
justments. Damage to the engine can
occur. Extend line to the length allow
by the line limiter and cut some grass.
Based on performance while cutting,
turn the mixture adjustment in
1/16-tum increments as follows:
• Clockwise until the engine hats good
power while cutting with no hesita­
tion.
Do not adjust by sound or speed, but
judge by how well the engine per­
forms while cutting.
• Counterclockwise if the engine has
speed but dies or lacks power while
cutting.
After completing adjustments, check
for acceleration. Reset if necessary.
Acceleration Check
If engine dies or hesitates instead of
accelerating, turn mixture adjustment
counterclockwise until you have
smooth acceleration. Recheck and ad­
just as necessary for acceptable per­
formance.
