CARBURETOR TROUBLESHOOTING
AND ADJUSTMENTS
In compliance with government emission
standards, the carburetor is calibrated to
deliver the correct fuel-to-air mixture to
the engine under all operating conditions.
The carburetor cannot be adjusted,
except for low idle speed. Carburetor
servicing should be performed by Sears
or other qualified service center only.
TROUBLESHOOTING
If engine troubles are experienced that
appear to be fuel system related, check
the following areas before adjusting the
carburetor.
1. Make sure the fuel tank is filled with
clean, fresh gasoline.
2. Make sure the fuel tank cap vent is not
blocked and that it is operating
properly.
3. Make sure the in-line fuel filter is
clean. Replace the filter if it is dirty or
restricted.
4. Make sure fuel is reaching the
carburetor. This includes checking the
fuel lines and fuel pump for restric-
tions or faulty components.
5. Make sure the air cleaner cartridge
and precleaner are clean and
properly installed.
6. Make sure the air intake screen,
blower housing and cooling surfaces
of radiator are clean and free of dirt
and debris.
7. Make sure cooling system is filled to
the proper level.
If, after checking the items listed above,
the engine is hard to start, runs roughly,
or stalls at low idle speed, it may be
necessary to adjust or service the
carburetor.
TO ADJUST LOW IDLE SPEED
1. Place the throttle control into the
"slow" position. Using a tachometer
set the low idle speed to 1200 RPM by
turning the low idle speed adjusting
screw in or out.
2. If proper operation is not restored after
adjusting the low idle speed, carbure-
tor servicing by Sears or other
qualified service center may be
required.

IMPORTANT: Never tamper with the
eninge governor, which is factory set for
proper engine speed. Overspeeding the
engine above the factory high speed
settng can be dangerous. If you think the
engine-governed high speed needs
adjusting, contact a Sears or other
qualified service center, which has
proper equipment and experience to
make any necessary adjustments.
