LCT Small engine leaks gas

When an LCT small engine is leaking gas, shut off the fuel supply and avoid using the engine until you find the source. Gas leaking from the carburetor is most often caused by a dried-out or missing carburetor gasket, especially when fuel is leaking from the bottom of the carburetor. The carburetor float bowl gasket and carburetor bowl gasket are also common causes of a leak at the bowl seam. Next, inspect the fuel tank for cracks, then check the fuel line for dry, split, or cracked sections. A brittle or cracked primer bulb can also cause a small engine fuel leak and should be replaced if it will not hold fuel. Stale or ethanol-blended fuel left in the carburetor can speed up gasket and rubber deterioration, making seasonal equipment more likely to develop leaks. Do not patch a cracked fuel tank, fuel line, or primer bulb. Replace the damaged part and clean spilled fuel before testing the engine. Enter your LCT model number to find the exact replacement carburetor gasket, float bowl gasket, fuel tank, fuel line, or primer bulb for your specific engine.
