Checking the spark advance

The ignition advance is determined electronically
on the basis of parameters known by the control
unit. For this reason it is not possible to declare the
reference values based on the engine rpm. The
ignition timing value is detectable any time using
the diagnostic tester. It is possible to check wheth-
er the ignition advance determined by the system
does in fact correspond with the value actually ac-
tivated on the engine, by means of the strobo-
scopic light.
Proceed as follows:
- Remove the spark plug.
- Remove the transmission crankcase.
- Rotate the driving pulley fan until the reference
marks between the flywheel and flywheel cover
meet as shown in the photograph.
