On my other kombi motors I run Dellortos which are duel barrel carburettors and they do not have a balance tube. As each barrel is operating one cylinder and that you can synchronised each barrel. As on a single barrel you have one barrel operating two cylinders and need to balance it out between the four cylinders. Even on a type 4 motor in a kombi Solex 34PDSIT-2 3 they are single barrel and also have a balancing tube.So maybe Ive been thinking about it all wrong. You can feel the single barrel feeding one cylinder at idle. When I put my straight thru muffler on, there is a definite " thump thump " idle -like a harley davidson (was a bit too loud for me so Im now back to Kadron quiet muffler)
I'm not saying or trying to convince you, that you need one. stating that duel carbs don't have a balance tube and singles do for a reason. Your carburettors may run fine without it and if your happy the way it runs, leave it and see how it goes. Haven't seen a set of Kadron copies so not sure if there is any difference with an original set. I take it your manifolds came with your carburettors and don't have any holes for a balance tube built into them?
I do have tapped holes in manifolds, I run my brake booster from passenger side and other side is plugged.
