Those shafts also have a weird way to set them. When installing a belt, hand spin the sprocket softly and it will teder todder around on its own from the counter weights. Kind of weird the way it rolls itself into the correct position on it's own weights. Just get everything set and balance shafts and then double check the shafts by slowly turning until it gravity rolls itself closely to the timing mark arrow, might be off a tiny bit, just do the rest by hand to point it exactly at the mark and install belt. I never knew this for a long time, I guess I just got lucky in the past.


Here is a demonstration on youtube that clears up my confusion. They use an EVO, but they are basically exactly the same motor.
