Loss of Power
Possible Cause
Grass too tall or wet
Mower deck clogged
Air filter clogged
Bad fuel, mower stored
without treating or draining
gasoline, or refueled with bad
gasoline
Fuel filter clogged, carburetor
malfunction, ignition
malfunction, valves stuck,
etc.
Vibration
Possible Cause
Grass and debris lodged
under the mower deck
Blades loose, bent, damaged,
or unbalanced by improper
sharpening
Mechanical damage, such as
a bent crankshaft
Mowing and Bagging Problems
Possible Cause
Mower is moving too fast for
lawn conditions
Cutting height adjustment
levers set at different
positions
Grass bag overfilled or
clogged
Mower deck clogged
Blades dull, worn, or
damaged
Wrong blades installed
Correction
Raise the cutting height (page 8),
cut a narrower swath, use a slower
ground speed, cut more frequently
when the grass is dry, or move the
Clip Director knob toward the BAG
position (page 5).
Clean out the mower deck.
Clean or replace the air filter
(page 11).
Drain the fuel tank and carburetor
(page 13).
Refuel with fresh gasoline

CARBURETOR MODIFICATION FOR HIGH
ALTITUDE OPERATION
At high altitude, the standard carburetor air-fuel mixture will be too
rich. Performance will decrease, and fuel consumption will increase. A
very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate your lawn mower at altitudes
above 5,000 feet (1,500 meters), have your servicing dealer perform
this carburetor modification. This engine when operated at high
altitude with the carburetor modifications for high altitude use will
meet each emission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease
about 3.5% for each 1,000-foot (300-meter) increase in altitude. The
effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
NOTICE
When the carburetor has been modified for high altitude operation,
the air-fuel mixture will be too lean for low altitude use. Operation at
altitudes below 5,000 feet (1,500 meters) with a modified carburetor
may cause the engine to overheat and result in serious engine
damage. For use at low altitudes, have your servicing dealer return
the carburetor to original factory specifications.
