CLEANING

The carburetor exterior surfaces should be
cleaned with a general solvent and dried with com-
pressed air before disassembly.
CAUTION: Be careful at carburetor cleaning not
to remove paint. Paint removal will cause carbu-
retor to rust very rapidly. Repaint if necessary.
Carburetor body and jets should be cleaned with
a carburetor cleaner. Follow manufacturer's in-
structions.
WARNING
Solvent with a low flash point such as gaso-
line, naphtha, benzol, etc., should not be used
as they are flammable and explosive.
CAUTION: Heavy duty carburetor cleaner may
be harmful to the rubber parts, O-rings, etc.
Therefore, it is recommended to remove these
parts prior to cleaning.
Inspect O-rings, diaphragms and gaskets.
