O.S. Engines 18TZ(S)-T - Manual (Page 18)

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.Therefore,it 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.
Silicone tubing
Connect suitable length
of Silicone tubing between
fuel tank and silencer.
Silencer
Fuel Tank
Before starting the engine, always
check the tightness of all the screws
and nuts especially those of joint and
movable parts such as throttle arm.
Missing retightening the loose
screws and nuts often causes the
parts breakage that is capable of
harming you.
STARTING THE ENGINE &
RUNNING-IN ('Breaking-in)
The following procedure is suitable for these
engines when the O.S. T-1040 tuned silencer
and a fuel containing up to 30% nitrome-
thane are used.
Fill the tank completely with fuel.
Temporarily remove the glowplug to check
that it glows bright red when energized.
