Attention: The ignition timing can only be checked, not set. In case of deviations from the specified values, it is necessary to determine the failed elements of the ignition system and replace them.
Warm up the engine. The operating temperature is reached from the moment the lower radiator water hose warms up. The oil temperature must exceed +60°C and the coolant temperature +80°C.
See drawing Y-1209
Connect the speed meter and stroboscope according to the operating instructions.
Start the engine, leave it to idle.
Aim the stroboscope at the arrow on the timing case cover.
Caution: Be careful with rotating pulley and belt.
With a normally set ignition timing, the V.M.T. 1 should look stationary and align with reference mark 2. It is recommended to highlight the marks with white paint.
