In order to check that the setting is correct, without tools,
accelerate the engine a few times with no load and check
the exhaust fumes.
Delivery of diesel fuel is correctly calibrated when the
exhaust gas is slightly coloured by smoke; change the
adjustment if necessary by turning the adjustment screw
(fig.99).

Engine power curves are reported at page 12.
