GS750 Carbs: gas "leak"

[Lens_cafe]

Ok, so i have a 1977 GS750. This is my first bike, and not very familiar with many things.
i currently have the air box off. i started it up, and noticed that fuel leaks out of the carbs when it's running, is this normal, or is it just leaking out because the air box isn't on?

It means you need to take the carbs off, strip and clean them and check that all the o rings / float valves are ok (probably best to just replace if you're not sure).

I would second all mentioned above. However, after I dipped and rebuilt (orings) mine, the float needle was stuck and allowed carb 3 to overflow. Gas should not overflow, ever, think "fire".
