The piston is at TDC twice for every rotation of the cam. 1 time at the start of the 4 stroke cycle/end of old cycle, 1 time at the halfway threw at the end of the compression stroke/start of power stroke.
When the timing gears are Dot to Dot it is TDC at the end of the cycle/start of new cycle. When the timing gears are both Dot at 12, it is at TDC, but the cam as at the end of the compression stroke/start of power stroke.
Which TDC should it be timed at ?
