Actually, the first notch to reach the pointer is at 16 degrees before TDC. It is the notch used to check the advance on the distributor. When static timing the distributor to TDC, you want to use the second notch.

Ironlegs, very good description and explanation but you need to change which notch does what.

...... A spark timing light can be applied to make fine adjustments to the timing of spark plug one at idle speed (first pulley notch) and sixteen degrees advance can be checked with the engine running at full speed.
