con-
trol
to
slightly
open.
A
CAUTION:
Make
certain
the

this).
NOTE:
If
the
engine
doesn
~
start,
limit
each
starting

30
seconds
before
repeating
the
start.
Never
operate
the
starter
motor
while
the
engine
is
still
running.
NOTE:
Some
unstable
running
may
occur
in
a
cold
engine.
This
condition
should
smooth
out
as
the
nOf77Ul1
operating temperature
is
reached
and
a
load
is
applied.
Allow a few
minutes
for
the
wann-up
at
a
comfortable
rpm
(approximately
1,000
rpm),
then
reduce
the
rpm
and
get
underway.
Low

Electric
Starting
Procedure
If
the
battery
is
discharged
and
too
low
for
a
normal
electric
start
but
not
completely
dead,
an
attempt
at
an
electric
start
can
be
made
by
using
the
Automatic
Decompression
Device.
This
device
works
by
holding
the
exhaust
valve
open,
and
is
normally
used
when
manually
starting
(hand-cranking)
the
engine.
NOTE:
The
Automatic
Decompression
Device
is
not
used
for
nOf77Ul1
electric
starting.
During
engine
operation,
the
pointer
on
this
device
is
in
the
operating
(9 o'clock)
position.
1.
Place
the
transmission
in
neutral
and
advance
the
throttle
con-
trol
to
slightly
open.
2.
Using
a
IOmm
wrench,
turn
the
hex-head
bolt
on
the
device
so
the
pointer
is
in
the
manual
starting
position
(see
illustration).

If
this
attempt
at
an
electric
start
does
not
start
the
engine,
then
a
manual
start
by
hand-cranking
will
be
necessary.
MANUAL
STARTING
(HAND
CRANKING)
When
installing
the
engine,
it
is
important
to
provide
enough
space
at
the
front
end
to
allow
for
manual
starting
(hand
cranking)
in
case
of
an
emergency
or
when
the
starting
battery
has
become
too
low
to
allow
an
electrical
start.
