Do not forget about safety measures when working with ignition.
Warm up the engine and turn it off.
Connect tachometer.
Connect the stroboscope and connect its control wire to the high voltage wire of the first cylinder (right in the direction of travel). Start the engine, let it idle.
If necessary, adjust the idle speed.
Point the strobe lamp at the edge of the inspection hole on the gearbox housing (on the left side of the engine compartment).
When the ignition is correctly installed, the notch (2) on the flywheel in the beam of the strobe lamp should be exactly under the mark - arrow (1) in the inspection hole of the clutch housing.
If the adjustment is not correct, loosen the clamp bolt on the bottom of the distributor or both bolts on the cylinder head.
Turn the distributor slightly to the right or left around its axis until the notch (label) on the flywheel will not coincide with the mark - arrow.
If the engine speed changes during the adjustment process, then it must be readjusted (it is possible).
Finally, tighten the bolt (s) and check the ignition timing again.
Ignition timing adjustment values
The table contains adjustment and reference values. With a quick check, there is a large spread of control values. It is necessary, however, to regulate as precisely as possible.
Attention: If the stroboscope has a control wire that connects to the high voltage wire of the first cylinder. then you need to pay attention to the quality of the contact. If the contact between the high-voltage wire and the spark plug is weak, the control unit or switch may be damaged.
