29.2 THROTTLE BODY “2”
The quantity of intake air is determined by the opening
of the throttle positioned on the initial part of the intake
manifold on every cylinder.
The air necessary for running at idling speed flows
through a by-pass channel, equipped with an adjusting
screw: turning this screw will vary the quantity of air which
is introduced into the manifold and consequently also
the idling speed.
A second screw allows the throttle closing to be adjusted
correctly. This will avoid any interference with the
surrounding duct; this screw must not be used to adjust
the idling speed.
