They have been completely stripped and separated and run through an ultrasonic cleaner twice. What needs doing, replace float bowl gaskets and do float height.
The jets have had previous owners damage them externally but internally they are clear(you could replace them from a kit). Also I noticed a couple of the mesh filters are damaged in the fuel feed for the floats. Available from Fowlers or just run without them. The carbs do look a bit scruffy on the outside but that's simply because I haven't finished them.
