sediment in pump cylinder or clogged intake ball check at bottom
of pump cylinder and discharge ball check In discharge passage. If plunger
is removed from cylinder, use care in installing to avoid damage to plunger
leather.
Correct air fuel ratio is provided by a "balance tube" cast in the
air horn. The balance tube should be checked each time the carbureter is serviced
to see that the passage is open. The object of a balanced carbureter is to
provide a constant air fuel ratio regardless of type, size or condition of
air cleaner. Should the cleaner become clogged, the capacity will be reduced
but the air-fuel mixture ratio will not be changed.
Excessive richness above 50 miles per hour may be caused by a clogged main
vent tube. After removal of rivet plug beneath float bowl with tool No. T109-42,
main vent tube can be removed and a new tube inserted with tool No. T109-70.
Care must he exercised in inserting new tube which must seat tightly. Use new
rivet to complete the installation.
Pump adjustment: Remove air horn assembly, back out throttle adjustment screw,
and place pump operating link in center hole of throttle shaft arm. Adjustment
can be made by bending horizontal portion of pump connector link, sothat top
of pump plunger shaft contacts lip of Indicator on pump stroke gauge T109-117S.
Correct travel is 24/64" on DTC1 and 26/64" on ETT1.
Pump stroke. adjustable for high or low temperature. Set to longest stroke
for cold weather, shorter stroke for hot weather driving.
Maximum economy and performance are secured only when breaker points, spark
plugs, valves and motor timing are set to manufacturer's specifications. After
motor is properly tuned, the following should be done to insure satisfactory
performance and economy:
(a) Float level must be set as above.
(b) Step-up rod in step-up jet must seat and move freely. When reassembling,
jet must be screwed in tight against seat.
(c) Step-up piston in body casting should not bind and must be free of dirt.
(d) Main metering jet can be replaced with leaner than
standard metering jets, for altitude or high test fuel.
Caution: Do not attempt to gauge metering jets with drills. These jets have
been flow-tested, to insure correct fuel flow.
