Cleaning and Inspection
The entire carburetor should be cleaned with a
general solvent and dried with compressed air be-
fore disassembly.
CAUTION: Heavy duty carburetor cleaner may
be harmful to the float material and to the rub-
ber parts, O-rings, etc. Therefore, it is recom-
mended to remove those parts prior to clean-
ing.
Carburetor body and jets should be cleaned in
a carburetor cleaner following manufacturer's
instructions.
Solvent with a low flash point such as gaso-
line, naphtha, benzol, etc., should not be used
as they are flammable and explosive.
Installation
For installation, reverse the removal procedure but
pay attention to the following.
CAUTION: Intake manifold and air intake hose
must be checked for cracks and/or damage. At
assembly, they must be perfectly matched with
the air filter housing, carburetor and engine or
severe engine damage will occur.
Make sure throttle valve piston groove passes the
inside protrusion in carburetor before closing the
carburetor cover.
Throttle valve piston groove must be aligned
with carburetor inside protrusion to allow
throttle valve piston to reach idle bottom
position. Otherwise, throttle valve piston
will be half opened leading to potentially
dangerous situation.
