TX
STARFLAME
ENGINE
GENERAL
INFORMATION
AND
MAINTENANCE
The
TX
Starflame engine
for
'73
has
been
completely
re-
designed
to
provide a 'winning' amount
of
horsepower and
sustain the
stresses
created
by
competitive
use.
It
is
all new
from
the
large
fins on the cylinder
head,
cylinder
and
crank-
case
to
chrome bore cylinders and tougher crankshaft
with
either 5
or
7 ball
type
bearings (Note specification sheet). The
goal
we
set
for
ourselves
was
to
get 160 Hp per liter and
we
did it.
Your
TX
Starflame engine
is
a completely
modif
i
ed
engine and
should
be
treated
as
such. The
following
items should
be
followed
if
you expect
to
receive maximum dependability
and power:
1.
Break-in, new engines - -
We
strongly recommend a
break-in period
of
30 minutes operating time. During the
first
15
minutes, maximum
throttle
should
not
exceed 4,000
RPM
with
no
load. The second
15
minute break-in period should
not
exceed 7,000
RPM
(1
/4
throttle).
During this break-in time,
use
N59G spark plugs.
After
break-in,
use
Champion N57 spark
plugs.
2.
Use
a good grade air-cooled
two
cycle engine oil and
premium
gas
of
not
less
than 98% octane mixed 16 : 1 (one
quart
of
oil
to
four
gallons
of
gas).
3.
After
one
to
two
hours
of
operating cylinder
head
retaining nuts should
be
torqued
to
13
ft.
lbs.
with
engine
COLD and weekly thereafter. (Note: refer
to
torque data,
page
40.)
4.
Keep engine and engine compartment clean. Engines
with
dirt,
grease,
and
oil
coating
will
not
dissipate heat properly.
A
clean
engine and engine compartment
will
also aid in the
location
of
a problem
if
it
should arise.
