Starting checks:
With a
cold engine,
do
not forget
to
push
in fully
the
dashboard
control as
soon
as the
engine is
warm
enough to run
satisfactorily
on
the
main
carburetter
out-
put
On warm days, if
the
engine is
not
stone cold.
it is
usually
possible
to
start it wtth
the dashboard
control
pulled
out only to the
halfway
position.
lf
an instant
start is not
made, check
possible
causes
as Íollows:
Remove
and clean the
starter
petrol
jet
2
(see
FIG
2:5). Blow
through it with
compressed
air or a
cycle
pump.
lf
the engine
has not
been run
Íor
some time,
prime
the
petrol pump,
clean
and reset
the sparking
plugs.
26
The
battery may
be low and
need recharging.
A
point
often
overlooked
is
that
while strong
enough
to
opeíate
the electric
starter
the current
may, in
consequence,
be
completely
absorbed,
leaving
none to
give
a spark
at the
plug
points.
lf
the engine is
hot and it
does
not start immediately,
depress the accelerator,
operate
the
starter,
and the
engine
should start within
a few
seconds, With
a hot engine
and
the ignition
and carburetter
coríectly
adjusted,
it is
normally
possible
to start
the engine
on the
pilot jet
output-that
is,
with
the throttle closed.

Slow-running
adjustment
1
This
adjustment is
of considerable
importance
and
depends
on the
mechanical
perfection
of both
the
engine
and carburetter.
Compressions
must
be
equal,
the
ignition system
in
good
condition,
and the
induc-
tion
system free
from
air leaks.
The throttle
pull-oÍf
spring
must
pull
the
throttle
back to its stop
(closed)
position.
All nuts
and screws
used in the
assembly
oÍ
the
carburetter
must
be tight.
2
Check that the volume
control
screw has
not
been
broken
or distorted
by
overtightening.
lÍ it has
a
new
screw
must be
Íitted.
3
Adjust the slow-running
as follows:
StaÍt
and run
the
engine until
it attains
its
normal
operattng temperature.
Set
the
throttle
adjusïing
scÍew
until the idling
speed is
on the high side.
4
Slacken
the volume
control
screw
until the
engine
begins
to hunt,
then
screw tt in
gradually
until
the
hunting
disappears.
5 lf
the engine
speed is
too high,
reser rhe
throttle
control
screw to
slow rt
down to
an idling
speed
oÍ
about
500 revlmin.
This
may
cause a resumption
of
slight hunting.
lf it
does, tuÍn
the volume
control
screw
gently
in
a clockwise
direction
until
the idlinq
is
correct.
Routine
maintenance:
The
carburetter must
be kept in
good
condition.
To
clean it remove
the
jets
and blow
through them
with
compressed air.
At the
same time
blow through
the
carburetter
channels.
All the
jets
are fitted
externally
and are easily
acces
sible
as follows:
1 The
main
jet
(Gg)
is screwed
into the
submerged
end
of
its
carrier
or holder
(5) (see
FIG 2
:4).
2 The
emulsion tube
(S)
is
held in
position
by ïhe
correction
jet
(a).
Access is
obtained
by removing
the
air cleaner
(see
FIG 2:3).
3 The
position
oÍ the
starter
air
jet
and the starter
petrol
jet
can
be seen in FIG
2
:5.
4 The
needle
valve
and
float
can be removed
by
unscrewing the
slot headed
screws
which
secure
the float
chamber
cover, and lifting
off the
cover.
Make sure that all
assembly screws
are tight
and
check that there is
no side
play
in
the throttle
spindle. lf
the
acceleration is
poor,
make
sure that the
jet
(Gp)
is
not choked although
this would
normally
affect the
general perÍormance,
NeveÍ interÍere
with the diaphragm
in
the accelerator
pump.
lÍ it needs replacing,
replace
the
whole
assembly, which is fixed
to the
carburetter
bv the
Íour
corner screws.
