4-4-4 Carburetor
At high altitude areas, standardized carburetor will cause thick mixed gas, drop the
output power and increase the fuel consumption rate for the gasoline engine. Gasoline
engine used at high altitude area can be improved by installing small-diameter main
metering jet of the carburetor and re-adjusting adjustment screw of idle mixing ratio. If
you often use the gasoline engine at the region of above 1,000 m, you can go to
authorized dealer of the Company to change the main metering jet and adjust the
carburetor. Otherwise, the gasoline engine shall be used by reducing power.
Even if being equipped with proper carburetor, every 300 m's rise in ASL will reduce
the power of the gasoline engine by about 3.5%. This reduction will be greater if it is not
equipped with proper carburetor.
If a carburetor applicable to high ASL application is equipped to a gasoline engine for
low ASL application, too thin mixed gas will cause the power reduction of gasoline
