VARIOUS ADJUSTMENTS
POINT
ADJUSTMENT.-
These
are lo-
cated
on
the
left
side of the
engine,
insi
de
the
mag neto
f lywheel,
which is protected by
a
cover.
Before
adjusting the points, their
condition
should be checked.
If they
are
burn-
ed or any
of them
show a perforation,
they
sho
uld be sanded
with fine sandpaper
or a
file
before be
ing
calibrated.
If
the
perforation
is very
deep,
or
if
the
points have previ ously
been sanded and
are
very worn, they should
be
replaced by
new
ones.
Whe
n installing
the
new poi
nts,
be sure to c
lean
them
very
well. The
points
generally have
a protective
layer of
grea0e,
wh
ich should
be
removed
once
they are
going to
be used.
When
in-
stalling
them
on
the support
disk,
be
careful
that
the
movea
ble point remai ns isolated,
that
is
to
say that
r~either
the point nor
the
connections
which reach
it are
grounded,
since this
would
c
au~e
a
sho
rt circuit pre-
venti
ng the
c
urrent from reach ing the spark
plug.
Under
these
conditions
we
can
now
pro-
ceed to calibrate the space
between points.
For
this operation
we turn
the propeller
shaft
to
a position
such
that the upper
part of
the
magneto
flywheel
cam
operates
against
the
shank
of
the
moveable
point. In
this
position,
loosen
the
screw
wh ich
hold
s the
fixed
po
int
and
move
it
in the direction
necessary to
obtain the
correct
calibration,
which
should
be
between
0.3 and
0.4
mm
. Then
tighte
n
the screw which holds the
fi xed
point and
check
the cali
b
ration
again.
