To
prevent
formation
of
gum
and
varnish in
gasoline
that
has been
standing
for
long
pe-
riods (several months),
there
is an alternative
to
draining
out
the fuel. It is
to
put
one
ounce
of
a
product
called
STABIL®
in
your
fuel tank
and fill the tank
up
to
the top.
This
will
keep
harmful
gums
from
forming
for
up
to
one
year
at a very small
cost.
An
8
ounce
can
will
cost
$3.00 and can
likely
be
obtained
from
your
local
Tecumseh
Engine
Distributor.

of
your
Tecumseh
engine
instructions.
Water in the fuel is a
fairly
common
cause
for
engines
not
starting,
or
running
roughly.
This
condition
is often mistaken
for
carburetor
ad-
justment
troubles.
Many
people
avoid
getting
water
into
their
fuel
by
buying
a
gallon
ortwo
at
a
time
and
constantly
replacing
it
with
clean,
fresh gasoline.
To
rid
your
fuel
tank
of
watery
or
stale fuel,
disconnect
the fuel line and drain it
into
a
container-keeping
it
away
from
all
flames, sparks, cigarettes,
or
hot
engine
parts.
The above is a
good
method
for
Winter
stor-
age
of
your
tiller, too. You
just
start
your
en-
gine
rigl;lt up and
consume
the
