David:

 A sketch on a piece of paper could be done in short order with benefits to all.

That makes sense. Unfortunately, it's not applicable in this case.  If it were that simple we woulda done dat already!  I am convinced that it would take 15 pages of text and a dozen photos to do it in a way that a reader could follow it, AND learn from it.  

What is the compelling reason for me to take the time from my business and other projects to do that--for the generosity of it?  

Gentlemen, this is only one of six forums/lists I visit regularly to answer questions about engine management.  There are only so many hours in a day and I'm already getting too many e-mails with direct engine management questions that DO need answering.  I like this group.  It's above average... sharp folks.  As all of us do, we participate on the level we can.  

Respectfully,

Walter Atkinson
