CARBURETOR BODY CLEANING
• Some commercially available chemical cleaners are
very caustic. These cleaners may damage plastic
parts such as the O-ring, the float, and the float
valve of the carburetor. Check the container for
instructions. If you are in doubt, do not use these
products to clean a Honda carburetor.
• High air pressure may damage the carburetor. Use
low air pressure (0.2 MPa (30 psi) or less) when
cleaning passages and ports.
Clean the carburetor body (1) with high flash point
solvent.
Clean thoroughly the following passages and ports with
low pressure compressed air.
– Pilot screw hole (2)
– Pilot jet hole (3)
– Pilot air jet (4)
– Main air jet (5)
– Transition ports (6)
– Pilot outlet (7)
– Main nozzle holder (8)
– Vent port (9)
CARBURETOR INSPECTION
FLOAT LEVEL HEIGHT
Place the carburetor in the position as shown, and
measure the distance between the float top (1) and
carburetor body (2) when the float just contacts the float
valve without compressing the valve spring.
If the height is outside the specification, replace the
float and the float valve and recheck the height.
To prevent serious eye injury, always wear safety
goggles or other eye protection when using com-
pressed air.
