Lawnboy leaking gas under/behind air filter

[dcfas]

I had a strange occurrence with my Lawnboy self propelled mower yesterday and this morning. I took it out of the shed, started it up, and walked it to the front of my house where I turned it off to gas it up. Once filled I tried to start it again and it wouldn't start.

Then I noticed it was leaking pretty steadily from what seemed to be under and behind the front corner of the air filter. It is a gold series engine by Honda @160 and only a couple seasons old.

So I took the air filter off and the plate holding the carb to see exactly where it was leaking from and turned the fuel valve to open and... no leak. Go figure.

I put it back together, started it up and cut the lawn this morning. Ran great- no leak.

Any thoughts? I expect more trouble.
