The perimeter of the crank flange is stamped with TC and a very clear hash mark. That mark should align with the seam in the case below the crankshaft (TC stamp should be facing down) to locate TDC on #1 & #2 cylinders. If memory serves correctly (which it may not), mine also has timing hash marks stamped into the perimeter of the crank flange. You index them against the case seam below the crank flange. It's been a number of years since I've looked since I have Pmags and set the timing with the engine at TDC.
