Has anyone used the Carter-Weber 2bbl carbs that Langdon sells? I have a 2x1 Offenhauser setup I am going to use on a 261 bored 0.030" over with a Howard's M4F cam and SM420 4spd tranny. I have a couple of Rochester 1bbl's that came with the intake, but I am leary of using them with all the problems I have heard/read about them. What type/model # carb do you folks think will work w/ my setup?
