it does not really matter how long the stop is. You also want to member DO NOT TURN LIKE CRAZY AND RAM THE PISTON AGAINST THE STOP. Use common sense. As you get close, slow down and ease the piston against your stop. The TDC as far as the pointer goes will work on exhaust or combustion stoke. The motor has four strokes, as you reach exhaust stroke, when the stroke is at TDC, the pointer or timing marks should be at zero, then as you reach the intake or combustion stroke, the TDC of that stoke will again be at zero on the timing mark.
