mark the choke plate and carburetor body with a
marking pen to ensure correct reassembly (refer to
Figure 6B-8). Also take note of the choke plate
position in bore, and the position of the choke
lever.

choke shaft when the screws were removed, Do
this before removing the choke shaft from carbu-
retor body.

Cleaning
A WARNING: Flammable Solvents!
Carburetor cleaners and Solvents are extremely
flammable. Keep sparks, flames, and other sources
of ignition away from the area. Follow the cleaner
manufacturer's warnings and instructions on its
proper and safe use. Never use gasoline as a
cleaning agent.
All parts should be carefully cleaned using a carbure-
tor cleaner (such as acetone). Be sure all gum depos-
its are removed from the following areas:
Carburetor body and bore; especially the areas
where the throttle plate, choke plate, and shafts
are seated.
е Idle fuel and “off-Idle” ports in carburetor bore,
main Jet, bowl vent, and fuel Inlet seat.
NOTE: These areas can be cleaned using a
piece of fine wire in addition to cleaners.
Be careful not to enlarge the ports, or
break the cleaning wire within ports. Blow
out all passages with compressed air.
* Float and float hinge.
e Fuel Bowl,
e Throttle plate, choke plate, throttle shaft, and
choke shaft.
NOTE: Do not submerge the carburetor in cleaner
or solvents when fiber, rubber, or foam
seals or gaskets, or the fuel inlet needle
