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.
When the engine starts, first allow it to operate
in short runs on its 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 overrich,
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°. Repeat this procedure again until five 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°.
Needle
The position of the needle-valve
when starting the engine.
Close the needle-valve approx.
30 deg after running the vehicle
every one full tank of fuel.
Repeat this procedure around
five 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. With the engine running, close the throttle
and allow it to idle for about five seconds,
then reopen the throttle fully. If, at this point,
the engine puffs out an excessive amount of
smoke and the vehicle does not accelerate
smoothly and rapidly, it is probable that the
idle mixture is top rich. In this case, turn the
Metering Needle clockwise 45-90°. If, on the
other hand, the engine tends to speed up
momentarily and then cut out abruptly when
the throttle is opened, the idle mixture is too
lean. Correct this by turning the Metering
Needle counter-clockwise 45-90°.With the optimum mixture control position,
light smoke is visible during high speed
running,and the engine rpm increases
smoothly during acceleration. Remember
that, if the engine is operated with the fuel/air
mixture slightly too lean, it will overheat and
run unevenly. As with all engines, it is
advisable to set both the needle-valve and
metering needle slightly on the rich side of
the best rpm setting, as a safety measure.
