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. When jets are very dirty or coated
with varnish and gum, replace them.
WARNING
Solvent with a low flash point such as gaso-
line, naphtha, benzol, etc., should not be used
as they are flammable and explosive.
Check throttle slide for wear. Replace as neces-
sary.
Check for fuel soaked into float no. 1; replace as
necessary.
Check float for cracks or other damages affecting
free movement; replace as necessary.
Inspect throttle and choke cables and housings for
any damage. Replace as necessary.
DISASSEMBLY AND ASSEMBLY

assembly procedures, it is recommended to use
