Yard Machines Lawn mower leaking gas
If your Yard Machines lawn mower is leaking gas, the problem is usually in the carburetor area, and the most common cause is a worn or missing carburetor bowl gasket. A damaged float needle is next on the list, since it may fail to shut off fuel and allow the carburetor to overflow. If gas leaking from the bottom of the lawn mower continues, check the carburetor gasket, then inspect the primer bulb for cracks or brittleness that can cause a lawn mower gas leak. After that, look at the fuel shut-off solenoid and fuel lines for leaks, loose connections, or pinholes. A stuck-open carburetor float can also cause the mower leaking fuel symptom, and in that case cleaning the carburetor may help, though a rebuild or replacement may be needed. Whether you are dealing with a carburetor leaking gas or a general lawn mower leaking gas issue, matching the exact part matters. Enter your Yard Machines model number on RepairClinic.com to find the correct carburetor bowl gasket, float needle, carburetor gasket, primer bulb, fuel shut-off solenoid, carburetor float, or complete carburetor for your mower.
