If your Huskee lawn mower is leaking gas, the problem is usually in the carburetor area. The most common cause is a worn, dried out, or missing carburetor bowl gasket, especially when gas leaking from the bottom of the lawn mower seems to trace back to the bottom of the carburetor. Next, check the float needle, which should shut off fuel flow when the bowl is full. If it is damaged, the carburetor can overflow and cause a lawn mower gas leak. A bad carburetor gasket is another likely cause, followed by a cracked primer bulb that leaks when pressed. You should also inspect the fuel shut-off solenoid and attached fuel lines for seepage, cracks, or loose connections. If those parts look good, the carburetor float may be stuck open, which can often be fixed by cleaning the carburetor thoroughly or by rebuilding or replacing it.

The float needle might not be shutting off the fuel. The float needle opens and closes the float valve to allow fuel to enter the float bowl. If the float needle is damaged, the carburetor will continue to fill with fuel until it overflows. If the float needle is defective, replace it.
Check the fuel shut-off valve for leaks, and ensure that the fuel lines fit tightly on the valve. If the fuel shut-off solenoid is leaking, replace it. In addition, inspect the fuel shut off lines for cracks or tiny holes. If a fuel shut-off line is leaking, replace it.
The float might be stuck open. If the float is stuck open, remove the carburetor assembly from the engine and clean it thoroughly. If the cleaning the carburetor is not effective, either rebuild or replace the carburetor.
