Checking and adjusting the ignition timing

1. Locate the timing mark plate located near the crankshaft pulley. T mark indicates top dead center (TDC). The indicator plate scale is in 2°increments and should have the correct alignment mark for your model. If this is not the case, count from the T mark the desired number of degrees to TDC and apply an installation mark. If the alignment marks are applied as shown in the figure, then instead of the plate, the model is equipped with an alignment indicator and instead of two cuts on the pulley there is one. Don't use the top notch (TDC) to set the ignition advance.

2. Locate the notch on the balancer or crankshaft pulley and mark it with chalk or a dash of paint (photo).



3. Start the engine, warm it up to normal operating temperature and shut it down. Turn off all lights and other additional electrical equipment, disconnect the radiator cooling fan electrical connector.

4. With the ignition off, connect the strobe input pin to spark plug #1 (use jumper wire). Connect the power wires to the stroboscope according to the manufacturer's instructions (photo).


5. Start the engine, aim the strobe at the alignment notch on the crankshaft pulley and note which of the alignment marks the notch on the pulley aligns with (photo).

6. If the notch does not line up with the appropriate mark, loosen the distributor bolt and rotate the distributor so that the notch lines up with the correct alignment mark.




7. Tighten the distributor bolt and re-check the ignition timing.

8. Turn off the engine and disconnect the stroboscope. Reconnect the spark plug wire and all previously disconnected electrical components.
