Where can you find a diagram and instructions on setting the timing on a 1995 Subaru Legacy wagon 2.2 motor?

Camshaft timing marks should be at 12 o'clock aligned with notches on timing belt cover above/aft of cam sprocket. Crankshaft should have timing line on crankshaft position sensor key at 12 o'clock thus causing the arrow on sprocket face to be at 3 o'clock and the sprocket keyway to be at 6 o'clock.

Frequently the arrow on the sprocket face is used as the incorrect crankshaft timing mark causing the camshafts to be 180 degrees advanced and a no-start condition where the motor cranks but fights itself on the compression stroke.
