The
lubricator
(3,
Fig.
43;
should be
given a turn
every rrooo miles, and
when
empty,
refilled with
the
correct
grease,
as specified
on
page
28.
The
rotor
incorporates a
small
carbon
resistance
sup-
pressor,
to
comply with
reg-
ulations
governing
telcvision
interference.
The
high-tension
distrib-
utor
requires no
attention
beyond an occasional
rviping
of
the
interior and
exterior
with
a clean, dry
rag.
lgnition Coil.
The
high-tension
ignition
coil
is mounted
on
the,front
of
the
engine,
as
illustrated
in
Fig.
45.
Connected
to
the
terminal
marked S.W.
(switch
wire)
is a
r mfd. condenser
to
reduce
electrical
interference
to
the
radio from the
ignition
system.
Care
must be taken
that
in
the
event
of a replace-
ment
coil being
fitted, that
the
condenser
is
correctly
connected
to the terminal
marked S.W.
and
not
to the output (C.8.)
terminal
of
the
coil.
The
outside
of
the
coil
casing should
be
kept clean;
misfiring is
occasionally caused
by an accumulation
of
dirt
around the terminals.
lgnition Timing.
If the
ignition
timing has been
deranged, it
can be
reset by reference
to
the
markings
on
the engine flywheel.
To
carry out
this
operation,
the crankshaft should
be rotated until
the
mark
'rlGN.
TDC.''
on
the flywheel registers urith the
small
pointer
_attached
to the
lower
bell-housing cover,
'when
No. r
piston
is
at
thb top
of its
firing stroke.
The
car
should be run up on a
ramp
or over
a
pit.
Examination
of
the lower
bell-housing cover (3,
Fig. 22)
will show the
small inspection
hole
on the side.
The
preferable method
is
to note
the
position
of the
pointer
and
then
to remove the cover.
Operate
the starter
motor
to
approximately
line up
the
flywheel marking;
replace
the cover for a temporary
check.
Remove
the cov_er an{
prise
the flywheel
round into correct
position,
then permanently
replace
the cover.
