    Thanks guys, Ric that link you gave was gold! A buddy of mine is rebuilding a 76 TNT 340that came with a tillitson carb. He was sold a VM34 with a 2.5 cutaway as a replacement but it looks like he needs a VM30. I will pass this on. Thanks again.

    in 77 the tnt used a 34 mikuin so I would use the 34mm a 30 is to small. a single 250 elan uses a 28 but I used a 32 on my twin 250 when I did a mukini swap, and then went up to a 34. use 34 on the 340! or try twin 30 mm on the 340 like the citation SS in 1980. start with those specs and then fine tune.
