TROUBLE SHOOTING
Carbureted engine
1.
Engine fails
to
start even
though
cranked
by
starter
at normal speed.
To get the engine started
qui
ckly
, it is most i
mportant
to
follow
the starting instructions.
a. Check that there is
fuel in the tank and
that
the charge
indicator
lamp lights up when the
ignition
is switched on.
b. Check that the
fuel
pump
is
feeding fuel
by
discon-
necting the fuel hose at the
carburetor
and letting the
starter turn the
engine
a few times
(without
depressing the
accelerator pedal).
c. Disconnect the cables from one spark
plug
at a time,
and operate the starter. A
powerful spark
should
then
jump the gap when the
cable is held close
to
the terminal
on the
plug
.
d. If
only
a feeble spark
is
obtained,
or
none
at all, check
whether the ignition
cables are
properly
plugged
into
the
distributor
and
ignition
coil. Check the low-voltage
con-
nections to the
ignition
coil.
e. Take
off
the
distributor
cap and wipe
off
any
mois-
ture. Check that the cap is
not
cracked and
that
the
break-
er points open when the engine is cranked.
Clean the
con-
tact surfaces.
f.
If
the
engine
has been cranked
for
some
time
without
firing, fuel mixture may have flooded the
cylinders
and
wetted the spark
plugs. Unscrew the spark plugs and
blow
the cylinders clean by cranking the engine
with
the
starter.
Dry
the plugs and check
that
the electrode gap is correct,
orfit
new plugs if available.
2. Engine misfires,
power
is
lost
or
engine runs
roughly.
Check that:
a.
None
of
the
ignition
cables has
come
loose.
b. None
of
the spark plugs is defective
or
in need
of
ad-
justment.
c. There is no arcing in the
ignition
system.
d. There is
good
contact
in the low-voltage
connections
to the
ignition
coil.
e. The
carburetor
has
not
iced
up
(may happen in
damp
weather). Remedy
by
switching
the
air
preheater
to
win-
ter setting.
f. The
oil level in the
carburetor
damping
cylinder
is
not
too low.
