Now connect glowplug battery lead to heat
the plug filament and start the engine.
Start the engine using an electric starter
making sure the engine rotation direction is
correct (counter-clockwise seen from the
crankshaft end).
In case of the 18CV-RMX
Starter Handle
Pull the starter handle briskly straight out
several times to start the engine.
When the engine starts, first repeat low
speed running and medium speed running
by raising and lowering throttle stick on the
transmitter to warm up the engine.
Aviod high speed running.
PRECAUTIONS
When starting the engine, with the hull out off the
water and no load on the engine, even below half
throttle, the engine can over-rev. Prolonged
running at higher throttle settings can result in
seizure of the connecting rod and crankpin. Never
run the engine with the throttle above the starting
setting with the hull out of the water and no load
on the engine.

Next, disconnect the glowplug battery and
try running the hull on the water. 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 hull on the water until one tank of fuel
has been consumed, then close the Needle-
Valve 30˚ and run the hull for another full tank
of fuel. 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˚.
Needle
The position of the needle-valve
when starting the engine.
Close the needle-valve approx.
30˚ after running the hull for
one full tank of fuel.
Repeat this procedure several
times.
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!
