The
type
D3034C
carburettor
has
certain
additional
features
These
include
a
power
valve
mechanism
to
improve
the
performance
at
high
speed
a
fuel
cut
off
valve
which
cuts
the
fuel
supply
when
the
ignition
key
is
turned
to
the
off
position
and
an
idling
limiter
to
maintain
the
emissions
below
a
certain
level
Sectional

of
the
two
types
of
pumps
are

is
located
in
the
centre
of
the

cleaner
uses
a

replaced
every

miles
Cleaning
is
not
required
and
should
not
be
attempted
The
cartridge
type
fuel
strainer
incorporates
a
fibre
clement
which
should
be
renewed
at
inervals
not
exceeding
40

The
fuel
lines
should
not
be
disconnected
from
the
strainer
when
the
fuel
tank
is
full
unless
absolutely
necessary
as
the
strainer
is
below
the
fuel
level
FUEL
PUMP
Testing
Disconnect
the
fuel
hose
from
the
pump
outlet
Connect
a
hose
with
an
inner
diameter
of
approximately
6
mm
0
024
in
to
the
pump
outlet
and
place
a
container
under
the
end
of
the
pipe
Note
that
the
inner
diameter
of
the
pipe
must
not
be
too
small
or
the
pipe
will
be
incapable
of
delivering
the
correct
quantity
of
fuel
when
testing
Hold
the
end
of
the
hose
above
the
level
of
the
pump
and
operate
the
pump
for
more
than
IS
seconds
to
check
the
delivery
capacity
The
capacity
should
be
I
400
cc

24
U
S
pts
in
one
minute
or
less
The
pump
must
be
removed
from
the
vehicle
if
it
does
not
operate
or
if
a
reduced
quantity
of
fuel
flows
from
the
end
of
the
hose
Remove
the
pump
from
the
vehicle
and
test
as
follows
Connect
the
pump
to
a
fully
charged
battery
If
the
pump
now
operates
and
discharges
fuel
correctly
the
fault
does
not
lie
in
the
pump
but
may
be
attributed
to
any
of
the
following
causes
Battery
voltage
drop
poor
battery
earth
loose
wiring
loose
connections
blocked
hoses
or
a
faulty
carburettor
If
the
pump
does
not
operate
and
discharge
fuel
when
connected
to
the
battery
then
the
pump
itself
is
faulty
and
must
be
checked
as
follows
First
make
sure
that
current
is
flowing
This
will
be
indica
ted
by
sparking
at
the
tenninals
If
current
flows
the
trouble
is
caused
by
a
sticking
pump
plunger
or
piston
The
pump
must
be
dismantled
in
this
case
and
the
parts
thoroughly
cleaned
in
petrol
If
the
current
does
not
flow
a
coil
or
lead
wire
is
broken
and
the
pump
must
be
renewed
A
reduced
fuel
flow
is
caused
by
a
faulty
pump
inlet
or
discharged
valve
or
blocked
filter
mesh
The
pump
must
of
course
be
dismantled
and
serviced
as
necessary
