FIRING TIME
ADJUSTMENT.- In
order
to
set
the
firing
ti
me
of
the
engine,
it
is nec-
essary
to
have
previo
usly
calibrated
the
poi
nts.
Once
this
requirement
is met,
the
engine's firing
time is
adjusted
by
the fol-
lowing
process:
On
the lateral
surface of the
magneto
flywheel
there
are
two fine
lines. In relation
to
the way the
engine revolves
(shown by
an
arrow on the flywh eel), the first line
cor-
respond
s
to the firing time and the second
one to
upper
neutral. To set
the engine's
firing
time,
make
the
first line
coincide
with
the
first line
with the mark (zero) which
is
on the
machined
outside
of the crankcase.
When the
flywheel
is
in
this
position, the
points should be
about to open, a condition
we
achieve
by
loosening
th
e
screws
which
hold the
support
disk to
the crankcase
and
by moving the
disk
in
the
direction
neces>
sary
to put the
points
in th
e
desired
position.
That
is
when
it
is
about
to open.
Be
especially
careful not
to
move the flywheel when loos-
ening
the
screws,
and
if
it moves, put it
once
more
in
the proper
position
before
moving
the disk.
Once the time
is
set,
tighten
the
disk
screws,
being
ca
reful
·
not to move the
disk.
Check
the firing time
again.
