It should look like this and the point of the pointer is what the timing it is set to.
The numbers are on the damper (crankshaft pulley).
The timing must be checked with a timing light. This device is connected in series with the No. 1 spark plug. The current that fires the spark plug also causes the timing light to flash.
The scale is located on the crankshaft pulley and a pointer is attached to the engine block so that the scale will pass close by. When the engine is running, the timing light is aimed at the mark on the crankshaft pulley and the scale.
