I'm picking up these carbs this weekend. All I know is they're Mikunis attached to a counterflow Eurospec head. Any identification of the model of these carbs... possible size...? I haven't found out too much about Mikunis. They need to be rebuilt and I plan on running them on my Mk3 using a mildly built OBD1 ABA head, so I'll need a new manifold I assume.
