STARTING.
Mark 12D and SE U nits.
Whon Cold.
Turn petrol tap to the
'ON'
position. Flood carburette1
float chamber by depressing tickler.
The carburetters fitted to these engines have a single lever control­
ling the throttle position, and to obtain a rich mixture for starting
it is necessary to tum the air filter shutter· to the clo�ed position.
Having flooded the carburetter, place gear control lever
m
the
''NEUTRAL"
or free engine position, open throttle lever, or twist
grip where fitted, about one third open and give kickstart lever two
or three sharp kicks. Having started the engine, the air filter can
gradually be returned to the fully open position as the engine
warms up.
When Hot.
Do not flood the carburetter or close the strangler shutter
fitted to air cleaner.
Failure
to Start.
If repeated kicks fail to start after flooding (when cold) ,
turn off fuel supply, open throttle wide, and clear cylinder
of excessive mixture by giving a number- of kicks to starter
lever. Now turn on fuel supply, and after opening throttle a little,
try again. If not sucessful, the sparking plug will probably be
found to be wet. If so, dry out, and turn over engine quickly after
having removed thy drain plug situated at bottom of crankcase, so
that accumulated n1ixture can be blown out. If still not successful
after having replaced drain plug the trouble must be found else­
where, and reference should be made to the "Fault Finding Chart."

instead of closing throttle, an easier start will be made
if
the machine has to stand a long time before again being
required.
Running In.
The useful life of a motor-cycle engine depends to a great
extent upon how it is treated during the first 500 miles, and
during this period the machine should not be driven at more than
30 miles per hour in top gear, 20 in middle, and 10 in bottom gear.
Do not allow the engine to labour in top gear, change to a lower
gear and ease back the throttle control.
GEARBOX.
The gear ratios are selected by the foot operated lever having a positive
stop for each gear position, "neutral" or free engine position being
obtained by pressing lever downwards from thefirst or low gear position.
