My John Deere 345 is leaking gasoline from on top of carb. Really can't see top, is there a fuel line that attaches to carb on top, or where can fuel be coming from?

Kawasaki FD620 OR 590? post the entire model I.D. https://www.jackssmallengines.com/jacks-parts-lookup/kawasaki-model-locator.aspx
Even so, the only way i could imaging gas coming out from up there or getting there, is a stuck or faulty inlet needle or float.
