Using 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.

Ď

. Operation of the Water Pump

1. Gradually open the choke after the engine warms up.
2. Set the throttle to the predetermined RPM.

ď
