Im running the dual Weber / Carter setup on my 235. I had big issue with the first 2 but now that they have been replaced the truck runs 1000 times better. I still do feel they are drowning the engine when you mash it. The secondaries possibly could be slightly toned down i think to help with that. Now that i have a bad set of carbs from the first go around i might try to take the secondary progressive linkage and play around and mod it to see if i can change the opening ratio. I will however only do that after early next season as i will first install a new camshaft with a different grind next spring. Possibly the too much fuel issue now might not be an issue with a more aggressive cam installed.
