Technical Winfield issue model A

I have a banger engine in my roadster project, Winfield head Inake and downdraft carb. I rigged up a temporary fuel system to get it running to and I noticed fuel leaking from the intake i inspected and found some cracks in the cast alum intake i was able to weld them and hopefully eliminate any vaccum leaks. But once I reinstalled there was still fuel leaking from two small holes on the underside that appear to be cast intentionally. They don't allow light to pass so I'm not sure what theyre for,I assumed they were there for production machining. But maybe not? So that's one problem. The other question is why is my intake flooding with fuel?
