I have fuel flowing from breather pipe - the one the goes into the air filter box. I assume its a stuck needle valve in the float chamber? But why would fuel flow out of this breather and not the overflow pipe?? Does anyone have a diagram that shows the internal ports in the carb body that would explain this ?

Yes stuck needle or too much pump pressure. The route of the fuel depends on the routing of the overflow pipes. I have often seen the pipes going up and over the carb as in this picture, in which case fuel is not going to drain safely is it!

+1 on the stuck float valve or over pressure.
The breather pipes that go to the air filter from the elbows should only be open when NOT at idle, the other breather pipes that come out sideways are only open when at idle. This is controlled by the vent valves which often jam up with crud.
The internals are shown here on the buckeye site page 6

Would I be right in thinking not all Stags came with vent valves? (before the V as in 175CD SEV).ChrisComment

Thanks all, turned out to be a much easier fix - swapped the fuel inlet and overflow pipes round and all is well. Should have finished earlier the night I did those. 🤣Comment

An easy fix, and at least you owned up to it, lol.Header tanks - you can't beat a bit of bling.Comment
