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.
Remember!
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.
Close the needle-valve approx.
30˚ after running the vehicle for
one full tank of fuel.
Repeat this procedure several
times.

•
Glowplug battery discharged or glowplug defunct.

of the electric starter.)
Remove glowplug, close needle-
valve and apply starter to pump
out surplus fuel. At this time cover
the plug hole with a rag so that
splashing out fuel may not come
into your eyes or mouth.
