Default setting timing on 80?

does anyone know the procedure for setting the timing on one of these little things. i had to change the rings and im not sure how to line the crank and cam back up when it gets put back together. is there an inspection hole somewhere in the case with a tdc mark on the crank and the cam?

these pages should do it. double check clearences, this is from an 1990 80 manual, but i use it all the time on my sons 07 raptor80 and its still going strong.
