6.

Double nut the carburetor studs and remove them.
See Figure 3.10.

NOTE: The insulator block and gaskets may fall out when

the studs are removed.

NOTE: The most likely reason to remove the insulator

block and its gaskets is to cure a lean running con-
dition. Inspect all removed parts carefully to iden-
tify the point where additional air is entering the
intake tract.

7.

Disconnect the choke linkage.

8.

Disconnect the throttle linkage and spring.

9.

Turn the carburetor upside down.

10.

Remove the afterfire solenoid by removing the two
screws (indicated by the arrows in Figure 3.11.).

NOTE: The screws are installed with a thread locking com-

pound. It may be necessary to use a #2 phillips
driver with a ratchet in order to get enough torque
to loosen the screws.

NOTE: There is an O-ring between the afterfire solenoid

and the carburetor. It is important that the O-ring is
in place when re-installing the afterfire solenoid.

NOTE: The carburetors are not inter-changeable from one

engine model to another. To help prevent carbure-
tor mix-ups, the engine model number is stamped
on the carburetor by the fuel nipple.
See Figure 3.12.

NOTE: Some red paint was smeared onto the carburetor

so that the numbers will stand out in the photo-
graph.
