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-turn increments as follows:
• Clockwise until the engine has 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.
