Inlet valve issues are seldom the fault of the float. Almost all used inlet valve needles look good, but they aren't if there is a leak. The seat can also be a problem. If you want to fix it, then clean the seat and replace the valve, then check the fuel level in the bowl.

Fill the carburetor with fuel and attach a hose as shown. Open the drain screw and observe the fuel level in the hose.
