PREVENTION FROM CARBURETOR ICING
CAUTION: When environmental temperature is higher than 10°C, always
return the shutter to normal (sun mark) setting. Otherwise the
engine may be damaged by overheating.
When the environmental temperature is low and humidity is high, water vapor
may freeze inside the carburetor and the engine drives unsteadily (carburetor
icing). Change the setting of the shutter as follows if necessary.
1. Remove the screw (1).
2. Change the direction of the shutter (2) as follows:
− Environment temperature is higher than 10°C: Set the shutter in normal
position (sun mark).
− Environment temperature is equal or lower than 10°C: Set the shutter in
anti-icing position (snow mark).
3. Tighten the screw.
