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

STARTING THE ENGINE & RUNNING-IN ('Breaking-in')
For long life and high performance, every
engine needs to be 'run-in' or 'broken-in'. With
care, running-in of the MAX-18TM can be
carried out with the engine installed in the
vehicle. Be sure to install the air-cleaner on the
carburetor and use a muffler-pressurized fuel
system.
The somewhat violent changes of vehicle
attitude that occur in off-road running,
combined with the fact that, in buggy type
cars, the fuel tank is often located some
distance from the carburetor, means that fuel
'head' at the carburettor can vary and upset
running.Thereforejt is recommended that a
muffler pressurized fuel feed system be used.
Never run your vehicle without installing the
air cleaner. Dust and dirt that may otherwise
be drawn into the engine will rapidly shorten
its life.
Fill the tank completely with fuel.
Temporarily remove the glowplug to check
that it glows bright red when energized.
Element glows when energized.
Pliers
Replace the plug when the
element does not glow or is
burnt out.
