be removed and a new tube inserted with tool No. T109-70. Care
must be 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, so that top
of pump plunger shaft contacts lip of indicator on pump stroke gauge T109-117S.
Correct travel is 26/64".
Pump stroke adjustable for high or low temperature. Set to longest stroke for
cold weather, shorter stroke for hot weather driving.
DASH-POT (EF1): Motors operating in connection with fluid couplings tend to
stall under rapid decelerating conditions unless the throttle is made to close
slowly. Slow throttle movement is necessary only the last part of the closing.
The dash-pot or decelerating pump acts as a snubber to the throttle, allowing
fast movement to almost closed position, then slow closing from that point
to the idle position.
Dash-pot operation is as follows: As the throttle is opened linkage raises
the plunger, filling the dash-pot cylinder with gasoline from the bowl. There
is little or no resistance to the gasoline as the cylinder fills. However,
when the throttle is released, the throttle valve closes rapidly until throttle
arm contacts dash-pot plunger arm. Then the plunger must be pushed to the bottom
of the cylinder before the throttle can close. A ball check located in the
lower end of the plunger shaft, seals the large upper openings and the gasoline
must leave the cylinder through the small metered hole in lower end of the
shaft. This reduces the rate at which plunger can be forced to the bottom of
the cylinder making the last part of throttle closing very slow. The adjusting
screw (in top of bowl cover) should be opened five full turns, from closed
position for average conditions. Under extreme driving conditions greater openings
may be necessary, al-though extreme dash-pot action will effect gear change
and not enough action will cause engine to stall.
lt.• sure plunger leather is soft and pliable and effects a gi.od seal
against the cylinder wall.
