CARBURETER
Correct float adjustment is important and should be made in the following way:
Place float gauge (No. T109-50) across the carbureter body. I'rrss float lever
clown to hold float pin against the bottom of the slot in the body casting.
Floats should just clear the projections on the gauge. If adjustment is necessary,
bend lip on float lever toward intake needle to lower level or away from the
needle to raise the float level.
If motor stalls while idling, set throttle lever adjusting screw so motor runs
between 500 and 600 R.P.M. Then set idle adjustment screw (EYC1) % to 11/a,
(EYC3) f to 11/4 turns open from closed position. If a vacuum gauge is available,
adjust to highest steady gauge reading.
Accelerating pump is actuated by the intake manifold vacuum and no adjustment
is necessary. However, be sure the bowl cover gasket and flange •gasket
seal to prevent any air leaks to the pump vacuum passages.
If engine misses when load is suddenly increased, remove pump jet and clean
with compressed air. However, it is usu-

ally advisable to replace the pump jet, as its cost is nominal. (All jets must
be seated gasoline tight.) This condition may also be due to damaged or worn
plunger leather in accelerating pump cylinder or discharge check in discharge
passage. 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 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.
A fuel filter is incorporated in the carbureter bowl casting. It should be
cleaned periodically by removing the filter bowl and element (small discs).
Soak element in acetone or a mixture of half and half Ethyl Alcohol and Benzol
until all foreign material dissolves. Then allow to dry. CAUTION-do not blow
off with compressed air which may damage discs.
