MAINTENANCE WORK ON CHASSIS AND ENGINE
Draining the float chamber of the carburetor
Following every wet-cleaning procedure, the float chamber of the carburetor
should be drained in order to remove any water that may have penetrated into
it. Water in the float chamber leads to engine malfunction.
Make sure you do this while the engine is cold. Close the fuel tap, and place a
cloth under the carburetor, which is capable of absorbing the leaking fuel. Unscrew
the plug [1] and clean it with compressed air. Then, mount the plug together with
the gasket, open the fuel tap, and check the float chamber for leaks.
Fuel is easily flammable and toxic. When handling fuel, be sure to exercise
the utmost caution. Never perform any work on the fuel system near open
1
flames or burning cigarettes. Always allow the engine to cool off first.
Immediately clean up any fuel which may have been spilled. Materials satu-
rated with fuel are also easily flammable. In case you ingested fuel or fuel
splashed into your eyes, consult a doctor immediately.
Dispose of the fuel properly.
Checking the float level *
Arrange the carburetor diagonally at about 60° so that the spring in the float
needle valve is not pressed together. In this position, the edge of the float
60°
should be parallel with the float chamber sealing surface (see illustration).
