Lawn Boy Lawn mower smoking
If your Lawn Boy lawn mower is smoking and blowing black smoke, the engine is usually running rich, which means the carburetor is letting in too much fuel. The most common cause is a carburetor problem such as a stuck carburetor float that stays open and floods the engine. Right behind that is a choke stuck closed, which limits airflow and throws off the air-fuel mix. In many Lawn Boy models, a worn or dirty carburetor can often be fixed with the right carburetor repair kit, but in some cases the full carburetor will need to be replaced. If your lawn mower engine smoking problem starts suddenly or gets worse under load, checking the carburetor first is the smart move. A mower running rich can foul the engine, waste fuel, and keep your mower from running cleanly. RepairClinic.com makes it easier to track down the cause and match the right fix, whether you need a replacement carburetor or a carburetor repair kit.
