O.S. Engines 18TM Revo - Manual (Page 20)

Note:
If the engine should need to be disassem-
bled (e.g. for cleaning or minor parts re-
placement), it is advisable to return the nee-
dle-valve to the original rich, starting set-
ting 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 or the fuel being changed,
especially to high nitro fuel, the complete
running-in should be repeated.
Warning!
Do not touch rotating parts, engine and si-
lencer when stopping the engine as they
become very hot, and contact with them
may result in a serious burn.
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.
