BRIEF CARBURETER ADJUSTMENTS
PUMP ADJUSTMENT: With throttle valve seated and connector link in place, pump
plunger should travel 16/64" from closed to wide open position. Adjustment
should be made by bending throttle connector rod at lower angle. Pump travel
can be measured by using universal pump stroke gauge T109-117S. Place base
of gauge on ridged portion of bowl cover so that projecting portion of pump
gauge rests on top surface of connector link at pump shaft. Hold gauge vertical.
The difference between the number shown by index mark on gauge, at wide open
and closed positions, should be 16.

METERING ROD ADJUSTMENT: Correct setting of metering rod.is important and
must be made after pump adjustment. Insert gauge (tool No. T109-102) in place
of metering rod, seating tapered end in metering rod jet. Hold gauge vertical
to insure seating. With throttle valve seated, press down lightly on piston
link directly over piston. There should be less than .005" clearance
between metering rod pin and shoulder in notch of gauge. Gauge must not drag
on pin. Adjustment can be made by bending lip on piston link so that it contacts
pump arm. (Use tool T109-105.) Remove gauge and install metering rod and
disk. Connect metering rod and spring.
