STARTING THE ENGINE
Be sure to use an electric starter to
start the engine.
Never fail to check the tightness of screws
and nuts, especially engine mounting and
moving parts (e.g. throttle lever).
Preparations
1
Installing the glowplug
Install washer on the glowplug
and insert carefully into
cylinder-head, making sure
that it is not crossthreaded
before tightening firmly.

Installing the propeller
First, install the propeller on the engine by
tightening the prop nut or spinner-nut lightly, and
make sure of the position where compression is
felt, turning the propeller counter-clockwise
slowly. Then tighten firmly as explained below.
For accurately centering the starter's rubber drive
insert, install an O.S. solid alloy spinner-nut to the
engine. (Available as an optional extra part).
Wrench
Alternatively, a spinner assembly, enclosing the
propeller boss, may be used, but make sure that it
isof sturdy construction and that the spinner shell
does not loosen when the starter is used.
Warning: When using a spinner assembly, make
sure that the notches in the spinner shell are large
enough to clear the propeller
blades and so do not cut into
and weaken the blade roots.
Tighten the spinner nut
firmly so that compression
is first felt around this
position (i.e. with blades
h o r i z o n t a l )
when turning
the propeller in
the direction of
arrow.

(e.g. O.S. Super Filter).
Do not let dirt or dust enter fuel can.
Fuel (model glow-plug engine fuel
Disconnect fuel line from the fuel inlet, and connect it to
