Poor acceleration may be due to damaged or worn plunger leather in accelerating
pump or pump check balls not seating properly. If plunger is removed from
cylinder, use care when installing to avoid damage to plunger leather.
Correct air fuel ratio is provided by a "balance tube" in the air
horn. The "balance tube" and vent passage must not be restricted.
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 he 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 be exercised in inserting new tube which mustseat tightly. Use new
rivet to complete the installation.
Pump Adjustment: Remove air horn assembly, back out throttle lever adjustment
screw, and locate pump link in center hole of throttle shaft arm. Place universal
pump travel gauge T109-117S on edge of bowl su that lip of gaugt extends over
top of plunger shaft. Turn knurled nut of gaup, until lip contacts top of plunger
shaft at closed throttle position. Take reading indicated on gauge. Repeat
with throttle wide open. Difference in readings obtained should be "26" (26/64" plunger
travel). Adjustment may be made by bending horizontal portion of pump lifter
link.
Seasonal Pump Adjustment: Three holes are provided in pump arm to meet seasonal
or climatic conditions. For high altitudes or extreme heat, use short stroke
(inner hole); win-ter setting: long stroke (outer hole) or intermediate stroke
(center hole).
