1. Take your foot off the accelerator
pedal.
2. Pause long enough for the engine revolutions to die down. This will
take from one to three seconds, according to speed attained.
3. Move the gear lever gently but firmly into the second position.
4. Continue with acceleration.
NOTE.The pause before changing up- is most essential. A long pause
will not matter; if too short, a noisy gear change will result.
Repeat the procedure from second to third gear at about 15 m.p.h. (25
k.p.h.) and from third to top gear at 20-25 m.p.h. (35-40 k.p.h.).
If this method is adopted and strictly followed, it does away with any
necessity for using the clutch once the car is in motion, provided the
freewheel is in use.
CHANGING DOWN.
To change down from top to third gear or from any gear to a lower gear,
proceed as follows : -,
Lift your foot off the accelerator pedal and at the same time move the
gear lever from the top to the third position; continue with the acceleration.
The movement need not be hurried but it is impossible to do it too quickly;
there must be no pause in neutral.
The same method of changing down applies in changing from third to second
gear; if a very rapid "change-down" is required on a steep hill
it is advisable to use the clutch in the normal manner.
GEAR CHANGING WITH FREEWHEEL
IN FIXED POSITION
If it is desired to drive the car with the freewheel in the "fixed"
position, the method of changing gear is somewhat different and the following
procedure should be adopted.
CHANGING UP. - After having set the car in motion as described in the
"starting from rest" paragraph above, continue on first gear,
speeding up the engine until 5-8 m.p.h. (8-15 k.p.h.) is attained and
then proceed as follows -
1. Depress the clutch pedal, at the same time taking the foot off the
accelerator pedal.
2. Move the gear lever into neutral.
3. Pause (count "one, two").
4. Move the gear lever into the second gear position.
5. Release the clutch pedal, at the same time pressing the accelerator
pedal gently.
To change from second to third speed, continue in second gear until about
15 m.p.h. (25 k.p.h.) is registered on the speedometer; then carry out
the same procedure as in the preceding paragraph. Repeat the operations
again from third speed to top, when approximately 20-25 m.p.h. (35-40
k.p.h.) is reached.
CHANGING DOWN FROM TOP TO
THIRD.
(1) Depress the clutch pedal and move the gear lever towards the third
speed position; it will not be possible to enter third gear immediately,
but if light pressure is maintained on the lever in the required direction,
third gear will be entered without noise after-a slight pause.
(2) Speed up the engine by pressing the accelerator pedal and let in the
clutch.
If this operation is carried out badly by virtue of failure to synchronise
the gear speeds correctly by accelerator manipulation, it will merely
mean that the change will take a little longer; however, if you do not
give correct synchronisation yourself the synchro-mesh mechanism will
do it for you, if you keep a steady pressure on the lever. Never snatch
the gear lever.
CHANGING DOWN FROM THIRD
TO SECOND AND FROM SECOND TO FIRST.
Use the same method as when changing from top to third speed. Synchro-mesh
does not operate on these two gears, but as a change is usually made at
very low speeds, "timing" is not of very great importance. Experienced
drivers will, of course, be able to change down at comparatively high
speeds by using the "double-declutch" method, which briefly
means that the two gears that are to be engaged are brought to as near
the same speed as possible by accelerator manipulation; so the higher
the road speed the more the engine must be speeded up.
IN CASE OF
TROUBLE ENGINE REFUSES TO START:
(1) Is the ignition switched
on?
(2) Is the cold start control properly set? (See Page 16).
(3) Is there petrol in the tank?
(4) Is there petrol at the carburettor?
(5) Is the petrol tank vent hose clear?
(6) Is there~ a spark at the plugs? (See Page 89).
(7) Is the distributor contact-breaker adjusted correctly?
(8) Is the throttle closed, i.e., is foot clear of the accelerator?
(Unless the engine is very hot, when starting may be assisted if the throttle
is opened).
(9) Is the distributor condenser faulty?
(10) Is the manifold petrol drain pipe blocked?
ENGINE STARTS BUT SOON STOPS:
(1) Is a carburettor jet choked?
(2) Is the carburettor or petrol pump filter blocked? (See Page 45).
(3) Is there a partial stoppage in the petrol pipe?
(4) Are the plugs faulty?
(5) Is there an intermittent short-circuit in the ignition switch wire?
(6) Is there water in the petrol?
(7) Is the cold start control properly set? (See Page 16).
(8) Is the carburettor float punctured?
ENGINE MISFIRES:
(1) Are the plugs faulty?
(2) Are the contact-breaker points maladjusted or badly pitted? (See Page
74).
(3) Is a valve sticking occasionally?
(4) Is the insulation of a high-tension wire porous?
(5) Is~ the coil defective?
(6) Is the ignition switch wire chafing any metal part of the car?
(7) Is the cold start control properly set? (See Page 16).
(8) Is the distributor condenser faulty?
LACK OF POWER:
(1) Are the tappets correctly
adjusted? (See Page 63).
(2) Are the piston rings worn or gummed with carbon?
(3) Is the ignition timed correctly? (See Page 63).
(4) Has the valve timing been disturbed? (See Page 61).
(5) Is a carburettor jet choked?
(6) Is the carburettor throttle opening fully?
(7) Does the engine need decarbonising and valves grinding? (See Page
61).
(8) Are the tyres inflated to correct pressure? (SeePage 70).
(9) Are the brakes binding? (See Page 39).
(10) Is the carburettor flooding?
(11) Is the cold start control being used correctly? (See Page 16).
(12) Are good petrol and recommended oil being used? (See Pages 6 and
36).
(13) Is the carburettor accelerator pump working satisfactorily? (See
Pages 53 and 60).
