If you google Dave Hottmann ruby timing, you should find plenty of info on setting the timing.
Basically the ruby being a simple engine would require the valve travel to be 90 degrees off of the piston travel.
You can get this fairly close by setting the eccentrics per the Ruby kit instructions which should be online also.
