Idle Transfer Slot on secondaries?

Do we assume you've adjusted the secondaries so they feed some air at idle?
This quite often allows you to close the primaries enough to get a clean idle with both mixture screws.
It usually doesn't take much of an increase to allow this to work.
Right. That's a good trick, too. But, SO FAR I haven't seen one where you have to expose any of the transfer slot on the secondary side. They are just too high up to do that. Heck, I had mine on my 450 adjusted square on all FOUR when I fired off my slant 6 to break in the cam. It popped right off.......at about 2700 RPM. lol I just left it there and it broke in fine. I readjusted it back later.
