Doesn't C&S already have the patent on that design? Not sure how Patrick gets away with that. More CFM with a smaller venture because the booster is not there. Looks interesting, but I don't hear anyone saying how good the C&S carbs are and these look to be very similar.
IF C&S has a patent, it's probably on such a specific feature that anyone can design something functionally similar w/o infringing on it.
FWIW, I've heard very mixed comments re C&S stuff. IIRC, more positive re alcohol applications, not so much for gas. Look pretty friggin' kludgey to me.
