Start the lawn tractor, and engage the parking brake.
Turn the fuel valve to the OFF position.
Place a container under the filter to catch
any spilled fuel.
Squeeze the hose clamps and remove
the lines from the filter.
Install the new filter with the arrow point-
ing toward the engine.
Be sure the clamps securely hold the fuel
lines to the new filter. Open fuel valve,
start the engine and check for leaks.
Dispose of the old filter and any spilled fuel properly.
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.
High altitude performance can be improved by a specific modification
to the carburetor. If you always operate your lawn tractor at altitudes
above 5,000 feet (1,500 meters) have an authorized Honda lawn
tractor dealer perform this carburetor modification.
