Honda Small engine leaks gas
A Honda small engine leaking gas usually has a damaged, dried-out, or missing carburetor gasket. If gas is leaking from the bottom of the carburetor, replace the carburetor gasket first, followed by the carburetor float bowl gasket or carburetor bowl gasket. A cracked fuel tank is another possible source, and a damaged fuel line can cause an engine fuel leak along the route from the tank to the carburetor. Inspect the primer bulb as well, since brittle rubber can crack and allow gas to escape. Stale or ethanol-blended fuel left in the carburetor on seasonal equipment can damage gaskets and other fuel-system parts, so drain old fuel before testing the repair. Do not operate the engine around spilled gasoline, and replace a cracked fuel tank, fuel line, or primer bulb rather than attempting to patch it. Before ordering, enter your model number to find the exact replacement part for your specific Honda small engine. Repair Clinic can help you match the correct carburetor gasket, float bowl gasket, bowl gasket, fuel tank, fuel line, or primer bulb to your machine.

The primer bulb may be leaking. Over time, the rubber of the primer bulb can become brittle and cracked, causing the bulb to leak gas. If the primer bulb is leaking, replace it. Do not attempt to patch or repair the primer bulb.

07 - Honda 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.
