Remove the rubber

use it to stop the mouth of
the

the cleored hole
in the ornr ond
insert the
corrugoted poper hose
(included in the

the
ex-
iension ond
the holder on the

ex-
houst monifold.
Give the
hose the required shope by
bending
it slowly ond corefully. Above
oll, ploce
it into
the holcier so thot
there is
o suff icient distonce
(wide enough to
insert o
finger) between it
crnd the exhot-tst monifold.
Tightening of

The cylinder heod
bolts should be tightened
in the running-in period before
the gosket gets
settled ond then
ofter every replocement of the
gosket, i.e., ofter
obout 1,000
kilometres' For

Alwoys turn the engine clockwise to eliminote ony ploy
in the distributor drive geor
ond to
ovoid loosening of the bolt. To relieve the
com-
pression resistonce, it
is recommended to bock
off the sporking plugs.
b) Stroboscopic method:
When using this method, the volues of the
bosic ignition timing ond
the odvonce con-
trolled by the centrifugol timing control (for
its
diogrom refer to Chopter 13.5) should be odded
upwhile multiplying bytwo
the odded upvolues
occording to the diogrom. Any effect of the
vocuum control must be
eliminoted by discorr-
necting the respective hose (connecting
the
distributor vocuum unit with the corburettor).
The meosuring procedure
is indicoted by the
diognostic equipment itself.
To Adiust ldling Speed
Use the oir-correction screw (speed
cor-
rection screw). The speed decreoses when ro-
toting the screw clockwise ond increoses when
rototing it onticlockwise.
Adiust the idling speed in occordonce with
the tochometer ond within the limits specified
in the following porogroph "To
Adiust ldle
Run". The engine must be wormed-up
before
storting the odjusting procedure (see
olso the
following porogrophs) ond its ignition must be
in perfect
condition (distributor
contoct-breoker
points, sporking plug
electrodes, ond ignition
odvonce).

Now connect the

(contoined in exhoust fumes). Use
the oir'cor-

comporoble with
the
specif ied corbon monoxide content, to
1+.2 +$.t.
After about one minute of
the continued idle
running recheck the odiustment ond
correct it,
if necelsory. Close the hole
with the
fost-idling
screw by driving in o
new plug with
its bottom
