Float Height Adjustment
1.
Place the carburetor on a level surface in the position
shown. In this position, the float tongue will lightly
contact the inlet needle valve pin without compressing
the pin spring.
2.
Measure the height from the float bowl mating surface
to the top of step in float (highest point) as shown. Both
sides of float should be parallel to each other. The
measurement should be made at the mid-point on the
top of the float using a vernier caliper.
When
measuring the height be sure the inlet needle valve
spring is not compressed .

Install the float bowl. Invert the carburetor and install a
Mity-Vac™ (PN 2870975) to the fuel inlet fitting. Apply
5 PSI pressure to inlet fitting. The needle and seat
should hold pressure indefinitely. If not, inspect needle
and seat and seat O-ring.
5.
Install the "E" clip on the jet needle in the proper
position. Inspect the needle closely for wear and
replace both needle and needle jet if needle is worn.
