be used when making float adjustments. Avoid apply-
ing any pressure on the floats which might compress
the tip of the fuel inlet needles.
The tip can
be
com-
pressed sufficiently to cause a false setting which will
affect correct level of fuel in the bowl.

Place a new air horn to main body gasket in
position on the air horn, then install the float needle
valve seats. (Be sure each needle seat and needle is
reinstalled in its original position.)
(5) Slide the right and left floats into position in
the air horn, then install the float fulcrum pins.
(Be
sure the marked float is installed on the pump side
of the air horn.)
See disassembly procedures.

After the floats have been installed, check the
float alignment, level and drop settings as follows:
Float Alignment Setting
(1) Sight down the side of each float shell to deter-
mine
if
the side of the float is parallel to the outer
edge of the air horn casting, as shown in (Fig. 9).
(2) If the sides of the float are not in alignment
with the edge of casting, bend the float lever by ap-
plying pressure to the end of the float shell with the
thumb.
To avoid damage to the float, apply only
enough pressure to bend the float lever.
(3)
After aligning the floats, remove as much clear-
ance as possible between the arms of the float lever
and the lugs of the air horn. To do this, bend the float
lever. The arms of the float lever should be as parallel
as possible to the inner surfaces of the lugs or the
casting.
Float Level Setting
(1)
With the air horn inverted, the air horn gasket
in place and the float needle seated, slide float gauge
(refer to specifications for carburetor being worked
on) between the top of the float (at outer end) and the
64x344

air horn gasket, as shown in (Fig. 10). Float should
just touch gauge (T109-106).
(2)
Check the other float in the same manner. If an
adjustment is necessary, bend the float arm using
Tool T109-22, until correct clearance has been ob-
tained. After bending arm, recheck the float align-
ment.
Float Drop Setting
(1)
Holding the air horn in an upright position,
measure the distance from the top of the floats (outer
end) to the air horn gasket, as shown in (Fig. 11).
This measurement should be 3 h inch. If an adjust-
ment is necessary, bend the stop tabs on the float
levers until the correct drop setting has been ob-
tained. Bend the tab toward the needle seat to lessen
the drop, or away from the seat to increase the drop.
(2)
After the floats have been checked and ad-
justed, continue to assemble the carburetor as fol-
lows:
(3)
Place the accelerator pump plunger lower
spring in the pump cylinder, then lower the air horn
carefully down on the main body. Care must be taken
