96 Kawasaki 300 Prairie leaking gas

[Dingybruad]

This is my 1st atv project... I'm use to trucks.

I have replaced both fuel lines and it's not leaking from there anymore. I cleaned out carb and it's not leaking from there. Nowhere round hose's and carb are wet...it looks like it's leaking from bottom of atv... I'm baffled. I hope someone can help

The lines from the vent on the carburetor go down to the bottom of the bike. It sounds like the needle and seat on the carburetor are leaking. This is really bad because it's possible to fill up the engine with fuel. To properly test the needle valve with the carburetor apart put the float on with the needle jet in place in the seat. When you hold the carburetor upright the float will drop down and you can blow through the fuel inlet. when you flip the carburetor upside down the weight of the float will now be pressing down on the needle and seat. You should be able to pull a vacuum on the hose attached to the fuel inlet on the carburetor and pull a vauum with your mouth, seal it off with your tongue and it should hold vacuum.

Most likely the fuel pump rubber seal . My kvf650 does the same thing when it's on a steep angle
