I don't know how to find out what I don't know, except

the hard way.  After I post the drawing of the leman port, I am
hoping that some real engineers will look at the timing, overlap and
so on.   Jerry

Jerry,  you do yourself a disservice. The fact the you are even trying to dercern the timing
BEFORE cutting means you are not in the "aluminum butcher" catagory! I understand the desire for
more power as well. Interestingly when I worked for Kawasaki they had an entire department that
scaled spy photographs to get new dimensions. They even had some high-sounding name for the
"guesstimators."
