DRIVING
FUEL
Now that pre-war quality fuels are again available owners are advised to use only the
best. The small economy that might be considered to accrue by using the cheaper
grades is more than offset by the advantages obtained by using only Number One
Grades.
FUEL SUPPLY
Two fuel feed taps are situated underneath the rear end of the petrol tank. (One each
side.) Both must be shut off when the machine is left standing for more than a few
minutes.
The tap plungers work horizontally. To open, the hexagon knob (marked " push on " )
is pushed towards the body of the tap. To close, press the round milled knob (marked
" push off " )
Normally, only use the tap on the right hand side of the machine and then the other
side will act as a reserve supply. Always re-fuel as soon as possible after being forced
to call upon the reserve (approx. ½ gallon), and then, at once, close the " reserve " tap.
It will be noted that, by fitting two petrol feed taps, it is possible to remove the petrol
tank from the machine without the necessity of first draining it of fuel.

See that there is sufficient fuel in the petrol tank.
See that there is sufficient oil in the oil tank.
See that the gear pedal is in the neutral position.
Push inward the hexagonal end of off-side petrol tap slide.
See that the air control lever is in the fully closed position.
On models with manual control, fully advance the ignition and then pull back the
control lever two-fifths of its total movement.
Open the throttle not more than one-sixth of the total movement of the twist grip.
Depress the plunger on the top of the carburetter float chamber until it can be
felt the chamber is full of petrol.
Raise the valve lifter lever and, while keeping it raised, turn over the engine several
times by depressing the kick-starter pedal, three times, the object being to free
the engine. (This only applies if the engine is cold.)
Depress the kick-starter until compression is felt, then raise the valve lifter lever
and ease the engine just over compression. Then, after allowing the kick-starter
pedal to return nearly to its normal position, give it a long swinging kick with the
valve closed. Flywheel momentum will carry over compression and the engine
should fire immediately. If it fails to do so repeat exactly the same process.
Do not allow kick starter to return violently against its stop.
The kick-starter mechanism must be allowed to engage properly before putting heavy
pressure on the kick-starter crank pedal pin. That means there are two definite
and separate movements when operating the mechanism by depressing the crank.
The first is a slow and gentle movement which ends when it is felt the quadrant has
engaged with the teeth on the ratchet pinion.
