GOOD WORDS
Further disassembly of the carburetor
is not necessary. The nozzle in the center
of the carburetor does NOT have to be
removed in order to properly clean the
carburetor. However, the nozzle can be
removed with a screwdriver if it is damaged
and needs to be replaced.

CLEANING AND INSPECTING
NEVER dip rubber parts, plastic parts,
diaphragms, or pump plungers in carburetor
cleaner. These parts should be cleaned
ONLY in solvent, and then blown dry with
compressed air.
Place all metal parts in a screen-type
tray and dip them in carburetor cleaner
until they appear completely dean, then
blow t hern dry with compressed air.
Blowout all passages in the castings
with compressed air. Check all parts and
passages to be sure they are not clogged or
contain any deposits. NEVER use a piece of
wire or any type of pointed instrument to
clean drilled passages or calibrated holes in
a carburetor.
GOOD

is worn and unfit for service. The bottom screw is new.
