IF YOUR AIR CLEANER IS OF
THE
DRY
ELEMENTTYPE (7 HP ONLY):
Check
the
element
at
the
start
of
each
day
that
it is used, and at least every 2
hours
of
operation
when
it
is used
continuously.
Vacuum
clean the
element
after
every 10
hours
of
operation.
Change it every
50
hours,
or
whenever
it
can't
be cleaned,
or
if
it is
torn-see

FOR ALL ENGINES
HOW
TO
ADJUST THE CARBURETOR
TO
CORRECT POOR TILLER PERFORMANCE
(DUE TO ENGINE STALLING, SPUTTERING,
SMOKING, OR TO LOSS OF ENGINE POWER).
If you
abruptly
open
the
throttle,
especially
af-
ter
the
first
few
hours
of
operation,
your
engine
might
happen
to
"stall,"
"sputter,"
or
"skip."
This
could
mean
one
of
several things. It
could
result
from
a
cold
engine, a
dirty
air cleaner, an
improperly
adjusted Idle
Adjustment
Needle
(rare),
or
more
likely, a
fuel-to-air
mixture
that
is
too
rich.
In either
situation
the
adjustments
are simple.
First, make sure
that
your
air
cleaner is
not
clog-
ged
up
with dirt. Clean it
if
it is.
Do
this
before
you ever make any
adjustments
on
your
carbur-
etor. Also, make
sure
that
the
spark
plug
is
clean,
properly
gapped and its
porcelain
is
not
cracked.
The
carburetor
adjustments
are
simple
too;
just
take
the
steps
below.
Please refer
to
the
photo
of
the
carburetor
on
your
engine
as
you
read these
instructions
(see
Photos
7/50
for
the
6
H.
P.
and 7/51
for
the
7 H.P. engine).
First, find
the
power
adjustment
screw
which
is
located
at the
bottom
of
the
carburetor
bowl
(see A in
the
photoj
for
the
6 H.P.
engine
and on
the
top
of
the
carburetor
for
the
7 H.P. engine.
