No washout in the MK2. The 1/4" stick is there to give the symmetrical wing a second place to contact the plan in addition to the main spar. The reason it is at an angle is to compensate for the taper in the wing from root to tip. I verified this before gluing parts by checking that the centerlines I drew on the ribs were level at both the root and tip. If the stick were not at an angle you would build twist into the wing.
