Got 2 matching (almost- a '59 & a '62) Rochester BC carbs on my 250 in my wagon. Rebuilt them. Got some vacuum pulling from the chokes (stove tubes?) Did a search & found conflicting answers (of course). So, what's the course of action here? Plug them & forget about it? Hook up some sort of stove tube to the manifold? It's an Offy intake & I don't see where that can be done. Other suggestions? It seems to idle smoother when I put my finger over the holes. Doesn't seem to have much effect on the road. Thanks.
