Operating the Engine
Positioning the Air-Cleaner Cover for
Cold or Warm Air Temperature
Important: Running the engine with the air-cleaner
cover positioned for cold-weather operation in normal
conditions can damage the engine.
The air-cleaner cover has 2 positions: the cold or normal,
ambient air positions:
Adjust the air-cleaner cover as follows:
•
When operating in a cold ambient air condition (cold
air temperature and humidity)—position the air-cleaner
cover with snowflake decal facing out
Note: Use this position if your machine exhibits
carburetor icing. Symptoms include the engine runs
rough at idle or low speed, and it discharges black or
white smoke in the exhaust.
•
When operating in a normal ambient air
condition—position the air-cleaner cover with sun decal
facing out
(Figure
8).
Note: Use this position if your machine is not exhibiting
carburetor icing.
