"Leak" in Carby?

[Pitst3r X4]

Hey Guys, Not long ago, I took my carby apart, cleaned it, put it back together and so on, when I went out the front to test it, all went well, had all the symptoms of a well cleaned carb, so I rolled it back into the shed and found a leak where the bowl joins to the carb! I don't know what to do about it as all the bolts have been done up tight, seals and gaskets are in the right place and it still leaks so I was wondering if any one could help me out? =[
I will post pics up soon.

Thanks in advance.

Thanks Swifty =)

Here are a few Pics.

I Know the breather looks like it leaking but it's definitely not.
I did go over all the screws, bolts etc. they were ALL TIGHT?!
I am thinking of taking it to the Bike shop and getting a professional to look at it but it is most likely the seals and or O-Rings
Anyone got any different ideas?
