ARBURATION PROCEDURE
Check of the starter control cut-out
In the event that the throttle valve potentiometer has been
replaced, removed or deregulated, before carrying out
any carburation procedure it is necessary to adjust it once
again, following the below instructions:
• Detach the connection rod between the throttle bodies;
• Using a tester, check that the potentiometer with the
closed throttle body indicates
values are different, loosen the two fastening screws
and reposition it correctly;
• Adjust the throttle bodies using the adjustment screw
until bringing the idling speed opening to 3,2°-3,6°;
• Attach the connection rod between the two throttle
bodies;
• Check that the by-pass screws are completely closed;
• Bring the RH side body's adjustment screw flush;
• Connect a vacuometer to the sockets on the intake
manifolds;
• Adjust the cylinders' equalization using the throttle
body adjustment screw;
• Check that the equalization is maintained in
progression;
• Check that the engine's idling speed is 1050 r.p.m.;
• Bring the oil to a temperature of 80°C;
• With the engine idling, check that the CO value is
between 3% and 3,5%. If this is not the case, adjust it
by varying the Trim.EPROM value on the software's
Active Test page.
• Check the r.p.m. and the equalization of the two
cylinders once again.
N.B.
Between the cylinders, a maximum unbalance
of 0,3% for the CO and of about 7 mbar for the
vacuum should be taken into account.
