I think you have written up a very nice explanation of what is involved...I might like to make one addition to it, however...  If you need to turn it more than 1/4 turn, I would definately take it to a shop to get the mixutre set...  Someone before you has jacked with it so much that you would be better off letting someone who understands the FI play with it (My Opinion)...  I would recommend very small adjustments at first, to see what changes there are, and after each adjustment, rev it to 3K.  This allows the adjustment screw to settle, and therefore give you a realistic baseline of what it needs to do...  Write me directly if I am loosing you at all...
