4-48 FUEL
Any damage to the orifice will result fuel
leakage and poor engine performance.
2- Install the drain plug with a NEW
gasket and tighten it securely with a 7/16"
wrench.
3- Install the inlet needle seat and gas-
ket.
TAKE CARE
to use the proper size
screwdriver to install the seat. If the inside
diameter of the seat is damaged the needle
valve will leak fuel causing a flooding condi-
tion in the carburetor.
4- Apply just a drop of oil into the seat,
and then insert the inlet needle into seat.
5- Position a NEW float over the needle,
and then slide a NEW hinge pin into place.
6- Hold the carburetor in a vertical po-
sition (up-and-down), and observe the float.
The float MUST be parallel (align evenly),
with the surface of the carburetor body. If
the float is not parallel
CAREFULLY
bend
the float ever so slightly, as shown, until the
correct positioning is obtained.
7- Slide the float bowl gasket over the
float and nozzle into position on the carbu-
retor base.
