I beleive Classic Motorsports had a recent article on tuning a TR6 which included a switch to the new Weber carbs. These are single choke, rather then the double choke carbs. For me I think an old sportscar should look the part, as well as drive. In this respect, to me, the new Weber carbs just don't look right. If it were mine I'd go with SU's or Weber DCOE's. Probably more money, and won't run as well without a lot of fettling, but they do have the classic look. Good luck.
