THROTTLE LINKAGE
Before connecting the throttle to its servo,
make sure that the throttle arm and linkage
safely clear any adjacent part of the airframe
structure, etc., as the throttle is opened and
closed. Connect the linkage so that the throttle
is fully closed when the transmitter throttle
stick and its trim lever are at their lowest
settings and fully open when the throttle stick
is in its fully-open position. Carefully align the
appropriate holes in the throttle arm and servo
horn so that they move symmetrically and
smoothly through their full travel.
NEEDLE-VALVE EXTENSION
The needle-valve supplied with this engine is
designed to incorporate an extension so that,
when the engine is enclosed within the
fuselage, the needle-valve may be adjusted
from the outside. Cut a commercially available
rod to the required length, bend one end to an
L shape, insert it into needle's center hole and
secure it by tightening the set-screw in the
needle-valve knob with 1.5mm Allen key.
Needle Valve Extension Cable Set (Code No.
72200080) is available from O.S. as an
optional part.

INSTALLING SILENCER
Apply silicone
sealant.
Exhaust Header Pipe
Exhaust Header
Pipe Nuts
Screw the exhaust header pipe in the
cylinder head to the bottom and secure it
with the nut. (A short screw in depth may
damage the threads of the cylinder head
due to vibration.)
1.
Screw the silencer on the exhaust header
pipe more than 8mm (10 turns) and secure
it with the nut. (A short screw in depth may
break the silencer or header pipe due to
vibration.) The distance between silencer
and cylinder head can be adjusted by
approximately 7mm by screwing the silencer
on or out the header pipe. Adjust the
silencer position by rotating the silencer.
2.
3. Apply silicone sealant to the threads to
prevent the silencer and header pipe from
loosening and leaking oil.
