                The manual system must be used at altitudes above 5000 feet, or whatever the

                manual prescribes for the engine type.

                8.9.2    Carburetor ice


                Carburetor ice is formed as a result of a drop in temperature due to:

                    -   Evaporation of gasoline

                    -   Expansion of air
                    -   Pressure drops in the venturi





                Carburetor  ice  is  dangerous

                because the engine can stall.

                Carburetor ice can occur both

                in  the  venturi  and  on  the

                throttle.
