FUEL
Although various 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 Premium 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. Push hexagon end
in
for O N .
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 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.
STARTING T H E ENGINE FROM COLD
Check that there is sufficient fuel in the petrol tank.
Check that there is sufficient oil in the oil tank.
Check that the gear pedal is in the neutral position.
Pull outward the plunger of off-side petrol tap.
Check that the air control lever is in the fully closed position.
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.
SINGLE CYLINDER MODELS
Turn ignition switch to IGN. Open the throttle to the smallest amount possible.
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.
T W I N CYLINDER (DE-LUXE MODELS)
Fully advance the ignition, then pull inwards the control lever one-eighth of an inch.
Operate the kick-starter by giving it a long deliberate swinging kick and the engine
should start.
The first slow and gentle movement is essential to avoid damage to the teeth of the
kick-starter pinion.
After the engine has started, slowly open the air lever until it runs evenly. Then set
the throttle so that the engine is running at a moderate speed (neither racing nor ticking
over) and allow to warm up. While doing this, check the oil circulation as detailed in
page 13. The machine can then be taken on the road.
T W I N CYLINDER (STANDARD MODELS)
Turn the switch to IGN, open the throttle to the smallest amount possible. Operate
the kickstarter by giving it a long deliberate swinging kick and the engine should start.
NOTE—Do not race up the engine from cold and do not flood the carburetter to such
an extent that petrol is dripping because then, in the event of a backfire, there
is a danger of such loose petrol igniting. This cannot possibly happen if the
starting instructions are carefully followed, but, in the event of a fire, there is
no cause for panic. Merely turn off the petrol tap to isolate the main supply,
open wide the throttle and turn over the engine by operating the kick-starter
pedal when suction will extinguish the fire.
