That's a slightly worrying post!
Check you have identified the correct parts to undo! The carbs are secured to the manifold with two circular clamps [item# 6]...
As you can see from this diagram too, there are 8 bolts that secure the manifolds to the crankcase, not four. Be careful loosening and tightening the manifold, as it can easily warp, and that's not something you can see by eye.
