That sort of explains a lot... I suppose the ISV just doesn't have the
"range" to drop the idle any further? The air that gets through a
basically closed idle screw (along with whatever air leaks I have) must
be enough to let the advanced engine still rev a little high. Since I'm
running about 20 or so degrees BTDC that would be why my idle is usually
around 1100 instead of a rock solid 950.
