Default Rotary valve for GEARS 2008 engine kit

I'm building the 2008 commemorative engine from the Oregon Gears 2008 show. It is single cylinder double acting with a rotary valve. I've spent some time trying to understand the drawing for the slots in the valve that control the inlet and exhaust timing. I expected to see one pair of slots at some angle to each other for the upper cylinder half and a mirror image pair at 180 deg for the lower. Instead there are three oddball angle callouts that I have not yet figured. Has anyone on the forum built one of these and can give me some hints?

Default Machining rotary valve

Iím a new member here and noticed your post on difficulty machining the valve. I was part of the GEARS organization and have prototyped and machined all of these engines from 2004 thru 2012. If you still need help on this, I have detailed instructions on this.
