VARIOUS ADJUSTMENTS
POINT ADJUSTMENT.- These are l
o-
cated
on the l
eft
side
of
the
eng
ine, insi
de
the magneto flywheel,
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
should be
sande
d with fine
sandpaper
or
a
file before being
calibr
ated. If the perforation
is very
deep
,
or
if the
po
ints have previously
been sanded and are very worn, they
should
be replaced
by
new
one
s.
Whe
n installing
the
new
points, be s
ur
e
to
clean them very
well. The points generally have a protective
layer of
gr
ea0e, which should be removed
once
they are
goin
g to be used. When in-
stalling them on the s
uppo
rt
disk
, be
caref
ul
that the moveable
po
int remains isolated,
that is to say that
r~either
the
point nor t
he
connections
which
reach it are
grounded
,
since this
would
c
au~e
a short circuit pre-
venting the current fr
om
reaching the
spark
plug.
Under
these conditions
we
can
now
pro-
ceed to
calibrate
the
sp
ace between points.
For this
operat
i
on
we turn
the
propeller
shaft
to a
pos
ition
suc
h that t
he
u
pp
er
part
of
t
he
ma
gneto fl
ywhee
l
cam
operates
aga
inst
the
shank of
the
moveable
point. In this position,
loosen the
screw
which holds the fixed
po
int
and move it in the
direct
ion necessary
to
ob
tain the
cor
r
ec
t calibration,
which
sh
ould
be between 0.3 and 0
.4
mm. Then tighten
the
screw
which
holds the fixed
point
a
nd
check
the calibration again.
