Kawasaki Small engine leaks gas
If your Kawasaki small engine is leaking gas, start by checking the carburetor, especially the area around the bottom of the carburetor. A dried-out or missing carburetor gasket is the most likely cause of a carburetor leaking gas. If the gasket seals the carburetor float bowl, replace the float bowl gasket or carburetor bowl gasket, which can also shrink, crack, or deteriorate over time. Next, inspect the fuel tank for cracks or a small fuel leak, then check the fuel line for dry, brittle, or cracked sections. Replace a damaged fuel tank or fuel line rather than attempting a repair. A leaking primer bulb is another common cause of a Kawasaki small engine fuel leak because its rubber can become brittle and split. Before working on the fuel system, shut off the fuel supply, let the engine cool, and clean spilled gas. Enter your Kawasaki engine model number to find the exact replacement carburetor gasket, float bowl gasket, fuel tank, fuel line, or primer bulb for your specific engine.
