Now connect glowplug battery lead to heat
the plug filament and start the engine.
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 the driving wheels clear of
the ground. The rich mixture will, under
these conditions, provide
lubrication and cooling, indicated by profuse
smoke from the exhaust.

Attention:
It is vitally important to set
the throttle at the correct
position before starting the
engine. If the engine is
allowed to run with the throttle too far open
under ''no load'' conditions (i.e. with the driving
wheels not in contact with the ground) it will
rapidly over-heat and may be seriously
damaged.

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.
