Why is gas coming out of my carburetor on my lawn mower?
A lawnmower fuel leak is often caused by the carburetor. The carburetor stores a small amount of fuel in the bowl on the bottom of the carb. The fuel is regulated into the bowl by a metering needle. If the metering needle becomes stuck in the open position, fuel will continue to flow until the fuel tank is emptied.

Why is my lawn mower not pumping gas?
The engine can’t get gas if the fuel filter is plugged or the carburetor inlet needle is stuck. Check the fuel filter (if equipped) by removing the fuel line at the carburetor. If you still don’t get any gas, the fuel line is kinked or plugged. And check inside the tank for any debris that might clog the outlet.
What happens when a carburetor float sticks?
One or more cylinders are not getting enough fuel or getting too much fuel when they are being fired by the spark plugs. This happens when the float is stuck, either in the open or closed position. The engine will stall, not idle smoothly or backfire once the carburetor float sticks.

What happens if you put too much gas in a lawn mower?
Filling your lawnmower’s fuel tank all the way to the top can cause gasoline to seep out of the cap vent hole. While this technically is not a leak, it may look like one, even appearing to come from the tank’s seam. This could make it hard to pinpoint actual leaks, so you should avoid overfilling if possible.
