Here are a few interesting comments from the Rennlist link above:

"The little Allen screws underneath the caps are needle-and-seat valves. Turning in will reduce the amount of fuel going to that pot, and also raise the pressure going into the other pots (a double-edged sword). Backing the needles out increases the flow to this pot, and lowers the pressure to the other pots. Be careful!"


"I read what he said as being -- adjusting any of the screws affects them ALL to some degree - the more you open one port, the less there is for the others, and vice versa. Think of it as a garden sprinkler with 8 outlets - block one, the other 7 get more; open one up, the less all the others get. Once you play with one, ALL will need some adjustment."

That last sentence is especially interesting. From what he is saying if I richen up #2 then at the same time I'll be very slightly leaning out 1, 3, 4, 5, and 6!
