Tecumseh Small engine leaks gas
Is your Tecumseh small engine leaking gas? First identify where the fuel is coming from and stop using the engine until the leak is fixed. A carburetor leaking gas from the bottom is most often caused by a dried-out or missing carburetor gasket, float bowl gasket, or carburetor bowl gasket. Stale or ethanol-blended fuel left in the carburetor can damage gaskets and contribute to a small engine fuel leak, especially on seasonal equipment. If the carburetor is dry, inspect the fuel tank for cracks, then check the fuel line for splits, brittleness, or loose connections. A cracked fuel tank or fuel line must be replaced, not patched. A leaking primer bulb is another common cause because its rubber can become brittle and crack over time. Look closely for gas leaking from the carburetor, around the float bowl, along the fuel line, and beneath the fuel tank before ordering parts. Enter your Tecumseh engine model number to find the exact replacement carburetor gasket, float bowl gasket, fuel tank, fuel line, or primer bulb for your specific engine.

07 - Tecumseh Carburetor
Over time, the carburetor may develop cracks due to the vibration and heat of the engine. If the carburetor is cracked, it will leak fuel. Inspect the carburetor for cracks or corrosion. If the main body of the carburetor is leaking, you will most likely need to replace the carburetor.
