ASPIRAZIONE
INDUCTION
To facilitate the operation, it is possible to note befo-
rehand and in order the play values revealed on the
strip of adhesive tape applied to the openings of the air
intake conduits.
These must anyway also be written in the table pre-
viously illustrated.
Rotate the crankshaft 360° by turning the central nut.
The rotation of the crankshaft must always be done in
an anti-clockwise direction.
The operation just described is completed when piston
n° 4 is in the Top Dead Centre position (T.D.C.) of the
compression stroke.
