Toro Lawn mower leaking gas
If your Toro lawn mower leaking gas has fuel dripping from the carburetor or gas leaking from the bottom of the lawn mower, start with the most common cause: a worn or missing carburetor bowl gasket. Next, check the float needle, since a damaged needle can fail to shut off fuel and let the carburetor overflow. Another likely source of a Toro lawn mower gas leak is a dried out carburetor gasket, especially when fuel is leaking from the bottom of the carburetor. A cracked primer bulb can also cause mower leaking fuel, and it should be replaced, not patched. If your model uses a fuel shut-off solenoid, inspect it and the connected fuel lines for leaks, cracks, or loose connections. Finally, the carburetor float may be stuck open, which can sometimes be fixed by cleaning the carburetor thoroughly, though a rebuild or replacement may be needed if cleaning does not help. Enter your Toro model number on RepairClinic.com to find the exact carburetor bowl gasket, float needle, primer bulb, fuel shut-off solenoid, carburetor gasket, float, or other replacement part that fits your mower.

02 - Toro Lawn Mower Float Needle
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.
