Place the base of the gauge on the ridged
portion of the bowl cover so that the
indicator rests on the top of the connector
link at the pump shaft. Hold the gauge
vertical. The difference between the numbers
shown by index mark on gauge at wide "open"
and "closed" throttle position should be
"16" (16/64"). Adjust by bending throttle
connector link at lower angle.
Metering Rod Adjustment
IMPORTANT: The metering rods must be
adjusted after the pump adjustment or
each time the carburetor is reassembled.
Models WGD-2231-S and WGD-2252-S
The metering rods must be adjusted after the
pump adjustment. Metering rod gauges are not
necessary for this adjustment. Throttle
valves must be seated in the bores of the
carburetor. Loosen metering rod arm set
screw and press down on the vacumeter link
until the metering rods bottom in the
metering rod jet wells. Holding the metering
rods in this position, revolve the metering
rod arm until the lip contacts the vacumeter
link and retighten the metering rod arm set
screw in this position (Fig. 11).

(WGD-2231-S)
Models WA1-2013-S, WA1-2009-SA,
and WA1-2113-S
Remove the metering rod and insert gauge (Tool
T-109-102 for WA1-2013-S and WA1-2113-S, and
T109-241 for WA1-2009-SA) in place of the
metering rod, seating the tapered end of gauge
in the metering rod jet. Hold gauge vertical
to insure seating. With throttle valve tightly
closed, press down on piston link directly
over piston until it contacts the pump arm.
There should be less than .005" clearance
between metering rod pin and the shoulder in
notch of gauge. Gauge must not drag on pin.
Adjust by bending lip on piston link; use
T-109-105 bending tool.
Reinstall metering rod, disc, pin, and
spring (Fig. 12).

(WA1 Type)
Model YF-2014-S
Close throttle until valve is seated in the
bore. Press down on upper end of diaphragm
shaft until diaphragm bottoms in vacuum
chamber. Metering rod should contact bottom
of metering rod well and metering rod arm
should contact lifter link between springs and
at supporting lug. Adjust by bending lip up
or down (Fig. 13).
