These
carburetors

present
several

distinct
features
of

importance
to

car

owner

A

summary
of

features
is
as
fol

lows

1

Secondary
throttle
valve
is

oper

ated

by
throttle
lever

High
power
and

good
acceleration
are

gained
with
com

bination
of
the

auxiliary
valve

4

The
throttle

opener

sys

tem

Except
FU
model

incorporates
a

servo

diaphragm
which

helps
open
the

throttle
valve
at

a

decreasing
speed
so

as
to

reduce

hydrocarbon
emissions

to

a
minimum

5
An
anti
d

eseling
solenoid

valve
is

installed
to

prevent
dieseling
When

ignition
key
is

turned
off
the

fuel

passage
involved
in
the
ow

system
is

closed
and
the
fuel

supply
is
shut

completely

The
solenoid
valve
also

serves
as
an

actuator
of
the
fuel
