Missing screw on carburetor

[leviathon51]

I seem to be missing a screw that sits right next to the idle needle on the carburetor. Unfortunately the diagam does not show a screw being there. When I run the engine or pump the fuel, gas comes out of the screw hole next to the idle needle. My engine model is 1041412YD, does it call for a second needle or just a screw? Thanks for the help!

I am not showing a screw there either, it is possible that the needle valve is not seating properly causing it to overflow. Try removing the carburetor and thoroughly clean.
