Always replace
badly
burned
or
pitted
breaker points.
A certain
amount of buil
d
up
or metal
transfer
occurs
under
normal
operating
conditions;
however, if t
his
occurs too
f
r
equent
l y
and
becomes
excessive,
the condenser may be at
f
ault .
Slightly pitted
points can be
dressed
down with a point f
ile,
al
though
thi
s
should be
done
only as a t
emporary
f
ix since
points
may tend to arc more readily after
f
il ing.
Re­
place points
at
fi
r st
opportuni
ty
after filing
.
If points are
oxidized,
rub a piece
of
coarse
cloth
be
­
tween the
surfaces
.
Dirty or
oily
points can be
cleaned
with a cloth but make sure no
particles
of lint
are left betw een
surfaces.
TIMING:
Engines are
equipped
with a timing
sight
hole in either the
bearing
plate or in
t
he blower housing.
Two
tIming
marks are
st
amped
on the flywheel
--the
T mark indicates Top Dead Center (TDC) while
th
e S or
SP mark indicates the Spark or Spark
Run
poin
t which
is 20° before TDC.
Two
methods
can be used
f
or tim
ing--the t
iming
l
i ght
method
is the more precise way of
achieving
exact t
iming.
The timing light can be used with magnet o ignition
systems;
however, a storage
battery m
ay
have to be used per timing
light
m
anufacturer's
instructions.
METHOD
1
- STATIC
TTIMING:
Remove
breaker point cover
and
remove spark plug lead to prevent
unintentional
startIng.
Rotate engIne by hand in direction of normal rotation (clockwise when viewed from blower housing
end).
Points
should
jus t begin t
o break
as the S mark appears in the
center
of the t
iming
s
ight
hole.
Continue rotating
engine
until
points
reach
m
aximum
opening.
Measure gap with feeler
gauge--gap
should
be .020" fully open.
If
necessary, loosen point gap adjustment screw and readjust gap to .020" full open.
MaximlDll gap setting can vary a few
t
housandt hs (.017
-
.0
23)
to achieve smoothest running.
Securely tighten
adjusting screw after timing.
METHOD 2

TIM ING LICJIT:
Several different types of timing lights are available-
-follow
m
anufact ur er ' s
mst.ructions
for t
ype
used.
The
f
ollowing
t
imi ng procedure can be used with
~
timing
l
i ght s :
A.
Remove
high
tension
l
ead
at spark plug
-
-wrap
one end of
a
short piece of fine wire around spark plug
terminal.
Reconnect l
ead
to terminal--free end of wire must protrude from under boot.
(Note: Step
A for
t
iming l
ights
with alligator clips--some lights have sharp prongs on spark lead-
-on
these sim­
ply push prong thru boot until i
t
contacts
metal connector.)
B. Connect one timing
l
i ght lead to the
wire
that has just been wrapped around spark plug
terminal.
C. Connect second timing lignr-lead to hot (ungr ounded) side of battery--see timing light instructions
f
or
battery
size, wiring, etC:- ­
D. Connect third timing light lead to ground.
E. Rotate engine by hand until S mark visible--chalk S line for easy reading.
F. Start engine, run at 1200 - 1800 RPM, aim timing light into sight hole
--light
should flash just as
S mark i
s centered
in sight hole or even with center mark on bearing plate or
blower
housing.
G. If timing is
off--remove
breaker point cover,
l
oosen gap adjusting screw,
shift
breaker plate until
