I have a John deer with a Kohler CV23, after carburetor cleaning job with air pressure, start right-up but 10 second later fuel just start to comes out from bottom left hole( please look at picture ) I recheck the needle and it is working properly. I just don稚 know why is doing this?

good indication that the needle valve isn't working properly under fuel pump pressure.
