FLOAT LEVEL Carbs. 3575—%" 3605-36I S—5/8"
CARBURETER 362S—5/64" from edge of casting.
IDLE SCREW SETTING 1/2 to 1¼ turns open
CARBURETER ADJUSTMENTS
If carbureter loads up after considerable service, check float level. Wear
on lip of float lever will raise float level. Float level in WI carbureters
can be reset by bending lip of lever away from needle to raise level, or
toward needle to lower level. In BB carbureter lip of float lever can be
bent down to raise float level or up to lower level. Only a very slight bend
is needed.
If motor stalls while idling, idle adjustment screw should be reset as instructed
in the specifications. Set throttle lever adjusting screw so motor idles
approximately 300 r.p.m. If these adjustments do not correct the trouble,
remove idle orifice tube and plug assembly in the BB carbureter and clean
tube and passages thoroughly with compressed air. In the WI carbureter, remove
low speed jet tube and clean with compressed air. Examine and see that tube
seats air tight in body casting top and bottom. If not, replace with a new
tube of identical specifications.
Poor acceleration may be due to damaged or worn plunger leather in pump,
sediment in pump cylinder or clogged check at bottom of pump cylinder. Examine
plunger leather and if necessary replace. Pump jets should be cleaned with
compressed air to remove the dirt and lint. However, it is usually advisable
to replace pump jets as their cost is nominal. All jets and checks must be
seated gasoline tight.
Excessive richness above 50 m.p.h. in the BB carbureter may be caused by
a clogged main vent tube. After removal of rivet plug be-neath float bowl
with tool No. T109-42, main vent tube can be removed and a new tube can be
inserted with tool No. T109-70. Care must be exercised in inserting new tube,
which must seat tightly. Use new rivet to complete installation.
Pump stroke adjustable for high or low temperatures. Set to longest stroke
for cold weather, shorter stroke for hot weather driving.
Pump Adjustment: (Carbs. 360.361 only) With pump connector link in lower
hole (short stroke) and throttle adjustment screw backed out, pump plunger
should travel 10/64" from closed to wide open position. Use gauge T109-1175.
Adjustment can be made by bending throttle connector rod at lower angle.
Maximum economy and performance are secured only when breaker points, spark
plugs, valves and ignition timing are set to manufacturer's specifications
as instructed above. After motor is properly tuned, the following should
also be done to insure satisfactory performance and economy:
(a) Float level must be set as instructed.
(b) Main metering jets or metering rods can be replaced with
leaner than standard parts for altitude or high test fuels.
(c) In the BB carbureter, step-up rod in step-up jet must seat and
move freely. When reassembling, jet must be screwed in tight
against seat.

Caution: Do not attempt to ga('opyrieht 1937
buge jets with drills. These jets have been flow-tested
to insure correct fuel flow
