TECHNICAL INFORMATION
SERIAL NUMBER LOCATIONS
There are two serial numbers, one for the engine and one for the
frame. Record the engine and frame serial numbers and date of
purchase in the space below. You will need this information when
ordering parts and when making technical or warranty inquiries.

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 tiller 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.
Possible Cause Correction
Engine switch OFF. Turn the engine switch ON
(page 6).
Choke lever not in CLOSED
(
E) position (cold engine).
Move the lever to the CLOSED
(
E) position (page 6).
Out of fuel. Add fuel and press the priming
bulb to fill the carburetor
(page 6).
Bad fuel, tiller stored without
treating or draining gasoline,
refueled with bad gasoline. Drain the fuel tank. Refuel with
fresh gasoline (page 16).
Spark plug faulty, fouled, or has
incorrect gap. Gap or replace the spark plug
(page 11).
Fuel filter restricted, carburetor
malfunction, ignition
malfunction, valves stuck, etc. Have an authorized Honda
servicing dealer replace or
repair faulty components as
needed.
Possible Cause Correction
Air filter dirty or restricted. Clean or replace the air filter
(page 10).
Fuel filter dirty or restricted. Clean or replace the fuel filter
(page 13).
Throttle cable out of
adjustment, broken, or bent. Adjust or replace the cable if
necessary (page 12).
Spark plug faulty, fouled, or has
incorrect gap. Gap or replace the spark plug
(page 11).
Possible Cause Correction
Faulty throttle control or cable;
throttle cable out of adjustment
or bent. Check throttle control parts,
adjust or replace cable if
necessary (page 12).
Idle speed is too high. Adjust the idle speed (page 12)
or have an authorized Honda
servicing dealer adjust idle
speed.
Clutch springs worn or clutch
system faulty. Have an authorized Honda
servicing dealer replace clutch
springs or replace or repair
other clutch system parts.
