ASSEMBLY - BOTTOM END
1. Insert slow jet into slow jet bore. See
thin bladed flat tip screwdriver into bore, and using slot at
top of slow jet, tighten until snug.
2. Place needle jet into main jet bore. See
sure end with chamfered edge and larger ID goes in first.
3. Insert needle jet holder into main jet bore, and using a 5/
16 inch wrench, turn hex until snug.
4. Thread main jet into needle jet holder. Using slot at top of
main jet, tighten with flat tip screwdriver until snug.
5. Install wireform clip into groove on pin side of fuel valve,
if removed. Using wireform clip, carefully hang fuel valve
onto tab of float, so that tip of rubber cone hangs flush
with top of float (the top being the side opposite the pivot
arm).
6. Place float into cavity of carburetor inserting fuel valve
into bore between pedestals. See
CAUTION
Tapping the float pin in from the rounded pedestal side
will result in damage that requires carburetor replace-
ment.
7. Insert float pin through squared pedestal and pivot arm
of float into rounded pedestal. Since the rounded pedes-
tal has an interference fit to ensure that the float pin is
securely held, always install pin from the loose side (in
the direction opposite the cast-in arrow). Using a small
center punch and hammer, carefully tap float pin until
ends are flush with outboard sides of pedestals.
8. Perform float level check as follows:
a. Place carburetor on a clean flat surface with the
intake manifold side down. See A of
b. Tilt the carburetor 15
direction until float comes to rest. See B of
20.
NOTE
The measurements will be incorrect if the carburetor is tilted
°
less than 15 or more than 20
c. Using a dial vernier caliper or dial caliper depth
gauge, measure the distance from the face of the
carburetor flange to the outboard edge of the float.
Be careful not to push on float while measuring.
d. If the measurement is between 0.413 inch and
0.453 inch (10.49 -11.51 mm), then the float level is
within specification. Proceed to step 9.
e. If the float level is not within specification, remove
the float, and referencing the table below, carefully
bend the tab slightly to adjust the float level. For
example, to increase the float measurement, bend
the tab toward the carburetor body. This will have
the affect of decreasing the amount of gas in the
float bowl after assembly.
f. Install float and check float level again. Repeat pro-
cedure as necessary until float level is within specifi-
cation.
9. Install new O-ring into groove of float bowl, if removed.
Be sure to thoroughly clean groove before O-ring instal-
lation.
