Husqvarna Lawn mower leaking gas

If your Husqvarna lawn mower is leaking gas, start at the carburetor. The most common cause is a dried out, cracked, or missing carburetor bowl gasket, especially when gas is leaking from the bottom of the lawn mower or right under the carburetor. Next, check the float needle, since a worn or damaged needle can fail to shut off fuel and let the carburetor overflow. A bad carburetor gasket is another likely source of a lawn mower gas leak, followed by a cracked primer bulb that seeps fuel when pressed. If those parts look good, inspect the fuel shut-off solenoid, valve, and attached fuel lines for leaks, then check whether the carburetor float is stuck open. In that case, cleaning the carburetor may help, but you may need a carburetor repair kit or a full carburetor replacement. Whether you are dealing with a mower leaking fuel, a carburetor leaking gas, or gas leaking from the bottom of a Husqvarna lawn mower, entering your model number on RepairClinic.com is the fastest way to find the exact replacement part that fits your machine.

02 - Husqvarna 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.
