sc rew where the centring jack is; this one
is only loosened;
-the c ylinder head is re volved round
the screw which was left in place; -the cylinder he ad is taken off;
-t he j a c ke t -m a inta i ni ng de vi c e -

.To be mounted:
-the rocker arm ramp:
-the oil-sealing of the cam-shaft;
-the flange of the cam-shaft ;
-the pi nion of the c am-shaft , which is
blocked with MOT 799 - 01 ;
-the cam-shaft;
-the stand of t he thermostat;
-the sparking plugs;
-the springs of the valves;
-the valves;
-the oil-seals of the valves, by using the
MOT. 1335 pincers.
The cylinder head is cleaned of the fit-
ting which is left stuck to it.
It is very important not to ge t the po-
sit io nin g surface of the fittings
s cratched.
Use Decapjoint to remove t he re mains
of fittings that are left stuck. The ab ove produc t is applied on the
cleaning are a; wait ca. 10 minutes, then
clean by means of a wooden spatula.

PRE S E NT
AT IO N
The system is made up of:
- electronic control unit;
- double ignition coil;
- four sparking plugs;
- spark plugs.
DES CRIPT IO N OF FUNCT IO NING PRINCI PL E
Accordi ng to the data received from
various sensors, but essentially according
to the revolution ratio and the load of t he
engine, the electronic control uni t will de-
termine the ignition advance; it will also
identify the cylinders that are set at the
upper center point and, consequently, will
command the re spective coil. This c auses the spark at the level of the
two cylinders t hat are at the upper center
point, thus interrupting the m ass-setting of
the respective coil. T
HE CO IL
The system c ontains a doubl e c oil, con-
trolled by the calculator.
Coil no. 2 has an electric connector (1) with
four ways, whi ch si m ultaneousl y produc e
s parks at cylinders nos. 1 and 4, when it i s
commanded by pin no. 32 of the i njection cal-
culator, and on cylinders no. 2 and 3 when it
is commanded by pi n no. 1 of the same cal-
culator.

SUGGESTIONS
♦♦
♦♦
Check if there is petrol in the fuel tank (do not rely on the
on-board in
dices). Check if it is the fuel recommended by
the manufacturer.
Disconnect the tube between the draining valve and the
intake collector and strangle it up. If the disturbances disap-
pear, the cause was the draining valve.
Connect the “CLIP TEHNIC” device to do this test in ac-
cordance with the usual manner of work.
Connect the tester “CLIP” and do the test corresponding to
the check-up of the rotation signal.
Gently touch the step-by-step engine in order to possibly
unbloc k it.
