IMPORTANT: Carburetor malfunctions are, in
many cases, caused by the presence of dirt, wa-
ter or other foreign matter in carburetor. To aid in
diagnosis, carefully remove carburetor from en-
gine without draining fuel from bowl. Contents of
fuel bowl may, then, be inspected for contamina-
tion as carburetor is disassembled.

ventilation hoses from flame arrestor, then re-
move flame arrestor.
IMPORTANT: Place a clean cloth in bores of car-
buretor to prevent dirt and foreign material from
falling into bores.

from throttle bracket and throttle lever anchor
