Set the throttle lever linkage so that the throttle ro-
tor is (a) fully open when the transmitter throttle
stick is fully advanced and (b) fully closed when
the throttle stick is fully retarded.
Adjustment of the throttle rotor opening at the idling
position can then be made with the throttle trim lev-
er on the transmitter.
(Select throttle-lever and servo-horn hole positions
that will avoid excessive pushrod travel causing the
throttle to bind at either end.)
THROTTLE LINKAGE
When adjusting the throttle lever angle, relative to
the rotor,hold the rotor at about half-way between
the open and closed positions while loosening
and tightening the fixing screw, otherwise the
rotor, rotor guide screw,throttle stop screw or
carburettor body may become burred and
damaged.
Note:
Before connecting the throttle-lever / servo linkage,
make sure that no part of the linkage interferes with
the internal structure of the aircraft or wiring, etc.,
when the throttle is fully open or fully closed.

Model engines generate considerable heat.
Do not touch any part of your engine until
it has cooled. Contact with the muffler
(silencer), cylinder head or exhaust header
pipe, in particular, may result in a serious
burn. Keep your hands and face away from
exhaust gas or you will suffer a burn.
Reminder!
Secure the silencer to the engine by means of two
fitting screws supplied after the engine is securely
fixed to a test bench or a model.
It is recommended to seal the fitting faces of engine
exhaust and silencer with silicone sealant.
