Suzuki 2 Strokes

Striped down my carburetors’ today the left one was flooding, leaking all over the left casing thought it would be a leaking float or a blocked needle. The float was leaking but also the bowl on the outside was concave on one side looked like it was sucked in, on the other carb. It was on both outer sides very strange never seen this before. Anyone seen it before or know why it happens

That must have been one heck of a strong vacuum to pull a rigid casting in. You will need a new float bowl by the way.
