Select the engineering Parameters icon on Axone, then that
on the Stepper position and start.
Bring the engine water temperature to 90°.
Connect a CO instrument tester to the exhaust plant.
The operation of adjusting the CO at minimum is recursive
and must take into consideration contemporaneously variations
in the Stepper position and the strength of the mixture.
The position of the Stepper must maintain a value between 30
and 40 pitches. If this value does not correspond, select the
Adatt icon with Axone. Bring the Stepper to within the
mentioned values with the Adjustment icon (Hammer and
Screwdriver) on the Stepper Manual. and bring the Stepper to
within the previously mentioned values.
Varying these two parameters using Axone (Carb. Adjustment
at minimum), try to obtain a CO reading on the tester of about
1.5 (lower values make irregularities at the minimum possible
while larger values, normally up to 3.0 - 3.5, improve the per-
formance, increasing the polluting gases however.).
