Stopping The Engine; Operation At High Altitude - Champion 100738 Mode D'emploi

100738 - 224cc ENGINE

Stopping the Engine

In an emergency, turn the engine switch to the "OFF"
position.
Under normal operation:
1. Turn the fuel valve to the "OFF" position.
2. Let the engine run until fuel starvation has stopped the
engine. This usually takes few minutes.
Important: Always ensure that the fuel valve is in the "OFF"
position when the engine is not in use.

If the engine will not be used for a period of two (2) weeks or
longer, please see the Storage section for proper engine and
fuel storage.

Operation at High Altitude

The density of air at high altitude is lower than at sea level. Engine
power is reduced as the air mass and air-fuel ratio decrease.
Engine power and equipment output will be reduced approximately
3½% for every 1000 ft. of elevation above sea level. This is a
natural trend and cannot be changed by adjusting the engine. At
high altitudes increased exhaust emissions can also result due to
the increased enrichment of the air fuel ratio. Other high altitude
issues can include hard starting, increased fuel consumption and
spark plug fouling.
To alleviate high altitude issues other than the natural power
loss, CPE can provide a high altitude carburetor main jet. The
alternative main jet and installation instructions can be obtained
by contacting our Technical Support Team. Installation instructions
are also available in the Technical Bulletin area of the CPE website.
The part number and recommended minimum altitude for the
application of the high altitude carburetor main jet is listed in the
table below.
In order to select the correct high altitude main jet it is necessary
to identify the carburetor model. For this purpose, a code is
stamped on the side of the carburetor. Select the correct high
altitude jet part number corresponding to the carburetor code
found on your particular carburetor.

Operation using the alternative main jet at elevations lower
than the recommended minimum altitude can damage the
engine. For operation at lower elevations, the originally
supplied standard main jet must be used. Operating the
engine with the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel efficiency and
performance.
