Invert the carburetor so the float tab rests on
the fuel inlet needle. Insert a . 01 0" feeler
gauge between float and float hinge towers. If
the feeler gauge cannot be inserted, or there
is interference between the float and towers,
file the towers to obtain the proper clearance.
Refer to Figure 6-15.
6. Install the bowl gasket and baffle gasket. Posi-
tion baffle gasket so the inner edge is against
the float hinge towers.

baffle gasket. Make sure the baffle gasket and
bowl are positioned properly to ensure a good
seal.
8. Install the bowl retaining screw gasket and
bowl retaining screw Torque screw to 50/60 in.
