O.S. Engines 32SX - Manual (Page 11)

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.
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.)
The exhaust outlet of the silencer can be rotated to
any desired position in the following manner:
Loosen the locknut and assembly screw.
Set the exhaust outlet at the required position by
rotating the rear part of the silencer.
Re-tighten the assembly screw, followed by the
locknut.

NOTE :
The standard expansion-chamber type silencer is
quite effective, but reduces power to some degree.
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.
