CO check
- CO checking may be necessary when an engine operation failure is detected or during engine idle
speed adjustment operations.
- This test must be carried out after washing all carburettor parts carefully, the air filter must be clean
and the ignition spark plug in good conditions.
1) warm up the vehicle travelling on the streets at about 50 km/h for ~5 minutes; time enough for the
automatic starter to exclude the circuit.
2) Shut off the vehicle only for the time required to carry out steps 3) and 4).
3) Connect a - 50 cm extension pipe to the exhaust fumes intake in the muffler.
4) Make sure the muffler and the pipe are adequately connected and tight. Insert the exhaust fumes
analyser probe into the pipe.
5) Connect the tester thermometer to the sump, using a cover with oil expressly prepared for probes.
6) Start the engine and before adjusting the idle speed, make sure that the oil temperature is between
70÷80 °C.
7) Wait until the idle speed stabilises for one minute.
8) Without operating the accelerator again and using the flow screw rev the engine at 1500±150
rpm.
