When the engine starts, first allow it to operate in short
runs at the very rich starting settings, with the glowplug
battery still connected and with its driving wheels clear
of the ground.The rich mixture will, under these
conditions, provide adequate lubrication and cooling,
indicated by profuse smoke from the exhaust.
Next, disconnect the glowplug battery and try
running the car on the track. If the engine stalls, open
the throttle fractionally, but try to keep the engine
running as rich as possible: if it stops because of
being excessively over-rich, close the Needle-Valve
30˚ and try again.
Run the car on the track until one tank of fuel has been
consumed, then close the Needle-Valve 30˚ and run
the car for another full tank of fuel.
Needle
The position of the needle-valve
when starting the engine.
Close the needle-valve approx.
30˚ after running the vehicle for
one full tank of fuel.
Repeat this procedure several
times.

To stop the engine, close the throttle to idling speed,
then shut it off completely with the trim lever on the
transmitter. To cut off the fuel supply, pinch the fuel
delivery tube to the carburetor.

If the engine should need to be disassembled (e.g.
for cleaning or minor parts replacement) it is
advisable to return the Needle-Valve to the original
rich, starting setting and check whether further
running-in time is required before the car is raced
again. In the event of any major working parts (e,g,
piston/cylinder liner assembly) being replaced, the
complete running-in should be repeated.
Remember!
It is vitally important to set the
throttle at the correct position
before attempting to start the
engine.If the engine is
allowed to run with the
throttle too far open under
"no load" conditions, it will
rapidly overheat and may be seriously damaged.
Remember!
Repeat this procedure until 5 more tanks of fuel have
been consumed, during which time the throttle may
be opened for brief bursts of increased power. If the
engine stops at medium speeds, close the Mixture
Screw 45-90˚.
