Manifolds (Saloon)
To
remove the inlet
and
exhaust manifolds it is
necessary to disconnect the air cleaner, carburetter
controls, petrol pipe, vacuum timing control pipe
and
exhaust pipe.
Inlet
and
exhaust manifolds can be removed as one
unit after releasing the two end nuts
and
four setpins
with special clamping washers.
Detach
the manifold
washer
and
if
damaged replace
on
reassembly.
It
will be noticed
that
the inlet
and
exhaust mani-
folds are separate castings.
At
the
point
where they are
joined immediately below the carburetter flange a
special design
of
"hot
spot"
is incorporated.
The
two
castings are held
in
position by four setpins, together
with a
joint
washer. Each manifold should be re-
assembled to the engine separately
and
then secured
together.

Manifolds (Sports)
There are two separate cast induction manifolds
1itted
to
the
Sports engine. Each manifold feeds two
inlet ports from one carburetter.
ยท Flanged
at
each end
the manifolds are bolted to the carburetter flanges
and
the
cylinder head.
Joining these two manifolds is a balance pipe.
The
function
of
this balance pipe is to even the gas
pressure fed
to
the engine.
The
exhaust manifold is identical to the Saloon
version, with the exception
that
there is
no
"hot
spot"
incorporated
and
that
it
is
not
connected directly
to
either
of
the inlet manifolds.

The clip beneath the fascia must nip the outer
casing
of
the choke control.
Throttle Linkage (Saloon)
The accelerator shaft is carried
in
a bearing
and
support which are attached to the toe
board
of
the body.
Its free
end
is
connected to a link attached
to
the
carburetter, this link has spring loaded ball
joints
at
each
end
and
these, together with the other moving
parts
of
the linkage, should
be
occasionally lubricated with
oil. See Fig.
3.
The strangler control is a
"Bowden"
type cable with
a friction control
knob
on
the
instrument panel.
It
is
important
that
the
clip, situated inside the car,
should be tightened sufficiently
to
grip the
outer
casing
of
the cable. This will ensure
that
the strangler cable
will operate correctly.
The
carburetter casting incorporates a bracket
bearing to
hold
a cranked
rod
which is connected
at
one
end
to
the
throttle
control lever
and
at
the .other end
directly
to
the accelerator pump.
Throttle Linkage (Sports)
The cranked accelerator pedal
arm
of
the Sports car
is identical to
that
of
the Saloon.
From
the
pedal
arm
a ball
joint
connecting link
joins
up
with the
throttle
connecting
arm
