Nolan,
I got the stacks this morning - they are not funnel like. Really they are
just extensions to the throat of the carb - the inside part of the "tube"
has a curved lip. A bit like this:

Except the slashes are curved.
Anyway, we can only but see what difference they make.
To the needles question: what is the operating range of a needle...? ie...
will the AAQ needles be ok with the carb running richer with the stacks
(assuming they make a difference)? or will I need to actually get another
set of richer needles?
