Stopping the Engine
In emergency, push the engine switch to “OFF” to stall the engine; to stop it in normal, do so as follows:
1.) Push the throttle lever to the right.
2.) Turn the engine switch to the “OFF” position.
3.) Turn the fuel valve to the “OFF” position.
High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be excessively
rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller
diameter main fuel jet in the carburetor and re-adjusting the pilot screw. If
you always operate the engine at altitudes high than 6,000 feet above sea
level, have your Powerhorse dealer perform these carburetor
modifications.
Even with suitable carburetor jetting, engine horsepower will decrease
approximately 3.5% for each 1,000 foot increase in altitude. The effect of
altitude on horsepower will be greater than this if no carburetor
modifications are made.
Exhaust Control System
While the engine is running, carbon monoxide, oxide of nitrogen and hydrocarbon will produce, and in certain conditions,
oxide of nitrogen and hydrocarbon will react with each other chemically and create a toxic carbon monoxide.
1. Maintenance
Maintain the engine periodically in accordance with the maintenance schedule. The maintenance schedule has
been created based on normal use and normal conditions. If using heavy load, operating in dusty and wet
conditions, or in extreme temperatures, service of the engine should be done more frequent.
2. Replacement of Parts
It’s recommended that you should choose parts which are manufactured by Powerhorse. Using a lower standards
or an incompatible part may impair the exhaust control system.
CAUTION

Sudden stopping at high speed under heavy load is not recommended. Engine damage
may result.
CAUTION

Operation of the engine at an altitude lower than the carburetor is jetted for, may result in
reduced performance, overheating, and serious engine damage caused by excessively
lean air/fuel mixture.
