d.
The
magneto
incorporates
a
built-in
pointer
and
a degree
wheel
with
sufficient
reference
to
assist
the
mechanic
in
magneto
timing
procedures.
Printed
upon
the
rotating
magnet
are
marks
to
indicate
magneto
neutral
and
magneto
"E"
gap
(8
).
(Refer
to
Figure
7A-30.)
Also
included
are
retard
angle
references
of
10,
15,
20
and
25
degrees.
These
marks
are
set
up
for
either
clockwise
(R)
or
counterclockwise
(L)
rotation
of
the
magneto
as
viewed
from
the
magneto
drive
end.
The
timing
tooth
of
each
large
distributor
gear
is
marked
with
red
paint.
(Refer
to
Figure
7A-31.)
NOTE
If
magneto
has
counterclockwise
rotation
then
the
marks
on
the
(L)
side
of
the
"K"
are
used
to set
timing.
A magneto,
correctly
timed
internally,
will
have
the
timing
teeth
of
the
large
distributor
gears
approximately
centered
in
the
timing
windows
at
each
end
of
the
magneto;
the
R ("E"
gap)
mark
which
is closest
to
the
"K"
or
keyway
up
position
indicator
on
the
rotor
in
alignment
with
the
pointer,
and
both
main
breaker
points
opening
all
at
the
same
time.
These
three
references,
"E"
gap,
painted
teeth,
and
point
opening
are
all
used
when
timing
the
magneto
to the
engine.
