.Use in Highland Areas

Operation in Highland Conditions

In highland areas (with a high ASL elevation), the air-fuel mixture

produced by a standard carburetor will be too thick and result in a

reduced engine performance and soared fuel consumption. For

operation in highland areas, the engine performance may be

increased by using a smaller diameter carburetor nozzle and

readjusting the carburetor idle speed. If the water pump is frequently

used in areas with a ASL elevation of more than 1800 meters (6000

feet), ask the local dealer to replace or readjust the carburetor

beforehand. Even if the engine is fitted with a carburetor nozzle of an

appropriate size, the engine power will still go down by about 3.5%

each time when the ASL elevation goes up by 305 meters (1000

feet). If no replacement or readjustment is ever made of the

carburetor, the highland effect of the engine output power will be

even more obvious.

CAUTION:

gUsing the water pump in areas where the ASL elevation is lower

than suitable for the carburetor nozzle will lead to a decreased

engine performance and overheating of the engine and even cause

serious damage to the engine due to an extremely thin air-fuel

mixture.

. Operation of the Water Pump

1. Gradually open the choke after the engine warms up.
