NOTE: It’s not necessary to ignite
all the plugs in a dual plug cylin-
der (two glow plugs per cylinder)
of Saito engines. It’s only neces-
sary to apply heat to the rear
plugs; the front plugs will ignite
once the engine reaches operating
temperature.
NOTE: A very common error is to
remove the glow plug igniter (or
on-board glow driver) too early.
It’s suggested that the igniter be
left attached (or left on in the case
of an on-board glow driver) until
the engine has been run up and
the high-speed needle valve has
been properly adjusted.
15. Using either a ”chicken stick”
or electric starter, spin the pro-
peller until the engine is running.
NOTE: When using an electric
starter, care should be taken to be
sure that the engine does not
become ”hydro-locked.” While
the electric starter will turn the
engine over, it may damage the
connecting rod or other compo-
nents. If the engine becomes
hydro-locked, simply remove the
glow plugs and turn the engine
over a few times with the chicken
stick or electric starter. The excess
fuel will be forced to exit the
engine via the cylinder heads.
16. Initial break-in:
After the engine starts, open the
high speed needle valve slightly.
DO NOT exceed 4,000 rpm for
the first ten (10) minutes of opera-
tion. This allows all parts to mate
properly with good lubrication.
Note: Due to the excessively
“rich” mixture setting, it may be
necessary to leave the heat source
attached (or left on) to the glow
plugs.
Subsequent runs may be made
while slightly leaning out the mix-
ture with each tank of fuel.
Generally, 40 minutes is consid-
ered sufficient for normal break-in
prior to the first flight.
17. After break-in:
If a test stand was used for the
break-in procedure, the engine
may now be mounted on the air-
craft using the integral motor
mount and mounting hardware
supplied with the Saito engine.
NOTE: Always utilize the
engine’s mounting spacers. Place
