MIXING
FUEL
The
two
cycle
engine
tho~
powers
your
W~-HP
requires
that
oil
be
mixed
with
the
gasoline
for
engine
lubrication.
Use
clean,
fresh,
regular
(leaded)
gasoline,
90
octane
or
higher
for
340s.
Use
premium
gasoline
in
400s
and
440s.
NOTE:
It
is
imperative
to
maintain
the
correct
ratio.
Too
much
oil
will
cause
spark
plug
fouling
and
excessive
smoke.
Too
little
oil
will
cause
engine
damage
from
inadequate
lubricati-on.
Scorpion
Snowmobile
oil
is
carefully
formulated
and
packed
in
special
containers
so
that
the
addition
of
one
container
of
oil
to
five
(5)
gallons
of
gasoline
will
result
in
the
correct
gasoline/oil
mixture.
Perform
the
following
steps
in
mixing
the
fuel:
1.
Put
21
/2
gallons
of
gasoline
in a
clean
container.
2.
Add
one
can
of
Scorpion
Snowmobile
oil.
3.
Shake
the
container
vigorously.
4,
Add
the
remainder
(2'/,
g<~llor.s)
of
gasoline.
5.
Agitate
the
container
thoroughly
again.
6.
Use
a
clean
funnel
with
a
fine
metal
screen
to
pour
the
fuel
mixture
into
the
gas
tank.
WARNING!!!
GASOLINE
IS
DANGEROUS.

fuel
can
cause
engine
failure
which
might
leave
you
stranded.
Do
not
attempt
to
mix
gasoline
and
oil
in
your
gas
tank.

(counterclockwise).
4.
Pull
the
rope
to
start
the
engine.
5.
Reposition
the
belt
guard
as
soon
as

engine
is
running.
NOTE:
Practice
this
procedure
at
least
once

be
familiar
with
it
if
you
ever
are
required
to
use
it
in
an
emerger1cy
situation.

TIPS
MAINTENANCE
1.
Check
over
your
snowmobile
regularly.
This
will
prevent
many
problems
from
developing.
2.
Always
turn
off
your
engine
before
attempting
to
make
repairs.
3.
Check
skis
and
other
steering
components
regularly
to
in-
sure
that
all
bolts
are
tight
and
in
good
condition.
Worn,
damaged
or
loose
steering
components
are
unsafe.
4.
Frequently
inspect
the
drive
belt
and
replace
it
as
necessary.
A
belt
that
has
been
worn
unevenly
or
"burned"
because
of
slippage
may
fail
without
warning.
Always
carry
a
spare
to
prevent
an
emergency
situation.
5.
Keep
fingers
from
between
sheaves
of
driven
clutch
when
removing
belt.
Movable
sheave
is
spring
loaded
and
could
in-
jure
your
fingers.
6.
Exercise
care
in
filling
the
fuel
tank
while
engine
is
hot.
Fuel
could
drip
or
splash
on
hot
engine
or
muffler
and
ignite.
Always
stop
engine
before
refueling.
7.
Be
sure
that
all
protective
devices
(hood,
belt
guard,
etc.)
are
in
place
before
operating
your
machine.
8.
If
your
safety
stop
switch
has
been
used
in
an
emergency
situation,
the
source
of
the
malfunction
should
be
deter-
mined
and
corrected
before
re-starting
the
engine.
9.
Before
checking
track
adjustment,
be
sure
that
the
track
is
free
of
all
particles
that
could
be
thrown
out
while
track
is
rotating.
Keep
hands,
feet
and
clothing
clear
of
the
track.
10.
Once
a
year,
the
driven
and
drive
clutches
on
your
snowmobile
should
be
disassembled,
cleaned
and
checked
for
worn
parts.
This
service
will
keep
your
machine
in
top
operating
condition.
NOTE:
Special
tools
and
training
are
required
for
such
main-
tenance;
see
your
Scorpion
Dealer.
11.
Check
fuel
tank
filter
regularly;
a
dirty
or
plugged
filter
will
cause
engine
damage.
Remove
filter,
clean
off
any
foreign
matter
and
blow
filter
out
with
air.
12.
Do
not
run
your
engine
at
high
RPM
with
the
drive
belt
removed
or
with
the
track
raised
off
the
ground.
Either
prac-
tice
may
be
detrimental
to
the
engine
and
hazardous
to
the
operator.
13.
In
the
event
of
replacement
of
the
gas
tank,
tighten
hold-
down
strap
only
until
it
is
snug
against
the
tank.
Over-
tightening
will
stress
the
tank.

SPARK PLUG USE/REPLACEMENT
Spark
plugs
will
require
your
attention.
The
primary
purpose
of
the
spark
plug
is
to
ignite
the
compressed
gas/air
mixture
in
the
cylinder,
coverting
it
into
thermal
energy.
The
condition
of
the
plug
will
determine
to
a
great
extent,
how
efficiently
the
engine
will
operate.
A
spark
plug
must
operate
under
a
variety
of
engine
conditions;
heat,
pressure,
vibration
and
foreign
deposits.
A
single
plug
has
not
been
developed
for
all
conditions.
The
plugs
installed
in
your
Scorpion
at
the
Factory
are
the
normal
heat
range,
i.e.,
best
suited
for
all
around
normal
service.
If
prolonged
low
speed,
light
duty
is
expected,
it
is
recommended
that
a
"hotter"
plug
be
used
to
prevent
plug
fouling.
(Consult
your
dealer).
If
prolonged
high
speed
or
other
heavy
duty
usage
is
anticipated
switch
to
a
"cold"
plug
to
prevent
pre-ignition
and
piston
failure.
The
appearance
of
the
spark
plug
is
an
extremely
important
guide
to
engine
performance
and
proper
spark
plug
application.
a. A
spark
plug
that
is
the
correct
heat
range
will
show
a light
tan
color
on
the
insulator
nose.
The
plug
is
retaining
the
correct
amount
of
heat
to
burn
off
unwanted
deposits,
but
not
enough
to
cause
damage.
b. A
plug
that
is
too
cold
will
not
retain
sufficient
heat
to
cause
cleaning
of
the
insulator
and
electrode
tip.
There
will
be
a
layer
of
unburned
residue
of
gummy
oil
deposits
or
black
fluffy
carbon
or
both.
The
color
of
the
insulator
will
vary
from
very
dark
brown
to
black.
c.
If
the
plug
is
too
"hot",
all
the
deposits
will
be
burned
off
and
very
possibly
the
insulator
and
electrode
will
begin
to
melt
from
the
heat.
The
insulator
will
be
white,
perhaps
shiny,
with
small
gray,
white,
blue,
green
or
purple
dimples
or
bum-
ps
near
the
tip.
The
very
tip
will
probably
be
distorted
since
it
is
the
hottest
point.
The
electrode
will
be
burned.
An
in-
creased
electrode
gap
in
a
very
short
time
is
an
indication
of
excessive
heat.
IMPORTANT!!
Always
start
your
machine
with
Factory
installed
plugs.
Use
hot
plugs
only
if
fouling
is
encountered
and
proper
carburetor
adjustments
do
not
correct
the
condition.
Switch
to
cold
plugs
if
burned
plugs
are
experienced
and
the
condition
can-
not
be
corrected
by
other
trouble
shooting
means.
See
Trouble
Shooting
section.
The
spark
plugs
should
be
checked
for
appearance
and
gap
each
250
miles
during
the
riding
season.
It
is
recommended
that
new
plugs
be
installed
at
the
beginning
of
every
snowmobile
season.

CHAIN
CASE
LUBRICATION
The
drive
chain
adiustment
is
obtained
automatically
through
the
use
of
tension
springs
and
pads.
No
adjustment
is
necessary
on
this
model.
The
only
maintenance
that
these
tension
springs
and
pads
need
is
that
proper
lubrication
be
had
at
all
times
in
the
chaincase
itself.
Be
sure
you
check
the
chaincase
oil
level
periodically
(at
least
every
30
days).
The
proper
way
to
check
the
lubricant
level
is
as
follows:
1.
Remove
inspection
dip
stick
located
on
lower
portion
of
chain-case
cover.
2.
Lubri-cant
should
register
in
the
knurled
section
of
the
dip
stick
with
the
dip
stick
screwed
all
the
way
in
(machine
sit-
ting
on
level
surface).
3. If
oil
level
is
low,
odd
a
medium
weight
oil
(suggested
SAE
1
OW30)
to
proper
level
through
dip
stick
opening.
4.
Replace
the
dip
stick
and
tighten
securely.

BRAKE
ADJUSTMENT
To
tighten
the
brake,
back
off
the
lower
nut
on
the
brake
cable
bracket
(located
behind
chaincase
on
support
bar)
and
tighten
the
top
nut
down
until
the
desired
engagement
is
achieved.
Rotate
the
driven
clutch
assembly
to
make
sure
that
the

turns
freely
and
that
the
brake
does
not
"drag".
Always
allow
at
least
y,"
free
travel
on
the
brake
lever
handle.
Check
the
brake
lining.
Be
sure
that
it
is
not
worn
out
or
covered

SKI
ALIGNMENT
Whip
snowmobiles
have
a
degree
of
play
in
the
steering
system,
caused
by
working
clearances
in
the
ball
joints,
spindle
to
ski
at-
taching
bolts
and
spring
to
ski
attachments.
If
this
play
is
not
properly
accounted
for
when
aligning
the
skis,
a
"toe
in"
or
"toe
out"
condition
could
exist,
which
results
in
poor
handling.
Ski
alignment
should
be
checked
periodically,
or
whenever
the
above
conditions
ore
suspected.
(See
illustrations).
1.
A
thorough
inspection
of
the
entire
steering
system
should
be
performed
before
realignment
of
the
skis.
Check
for
loose
bolts,
tie
rods,
steering
arms,
spindle
to
ski
attaching
bolts,
bent
members,
etc.
2.
With
the
machine
resting
on
the
floor
or
groUnd,
grasp
both
ski
handles
and
pull
skis
together
to
remove
the
system
"play".
3.
Measure
the
distance
between
the
inside
edges
of
the
skis,
both
front
and
back
(in
area
where
springs
attach
to
skis).
4.
This
measurement
should
be
equal.
5.
To
adjust,
loosen
the
lock
nuts
on
the
,tie
rods
and
rotate
the
tie
rods
to
correct
the
misalignment.
Both
tie
rods
should
be
adjusted
equally
to
assure
that
the
handlebar
will
properly
align
with
the
skis
in
the
straight
ahead
position.
This
is
very
important.

SUSPENSION ADJUSTMENT
The
rear
spring
adjustment
governs
preload
and
should
be
correlated
with
the
weight
of
the
rider
or
riders
normally
using
the
machine.
Too
much
spring
tension
will
result
in
a
harsh
ride
and
increases
the
weight
carried
on
the
skis,
thus
increasing
steering
effort.
Too
little
spring
tension
will
result
in
the
bottoming
out
of
the
suspension,
a
harsh
ride
and
shortened
life
to
the
suspension
components
will
occur.
1.
The
proper
spring
tension
may
be
obtained
by
having
the
rider(s)
sit
on
the
machine,
in
the
normal
sitting
position
and
measure
the
distance
between
the
floor
and
the
bottom
of
the
running
board
at
the
rear
of
the
machine
(either
side).
