Ryobi Lawn mower smoking
If your Ryobi lawn mower is smoking, especially if it is blowing black smoke, the engine is usually running rich because the carburetor is letting in too much fuel. On most mower smoking complaints, the first thing to check is whether the carburetor float is stuck open, which can flood the engine with gas. Next, inspect the choke to see if it is stuck closed, since that limits airflow and throws off the air-fuel mixture. In many cases, a Ryobi lawn mower engine smoking problem comes down to a worn or dirty carburetor that needs cleaning, rebuilding, or replacement, which is why the carburetor and carburetor repair kit are the most common fixes. If your lawn mower is smoking and the exhaust is dark, that points more to excess fuel than to an ignition problem. RepairClinic.com makes it easier to narrow it down and get the right small engine parts fast.

If the carburetor float is stuck open, the engine will get too much fuel. Similarly, if the carburetor choke is stuck closed, the lawn mower engine will not be able to draw in enough air to create the proper air-fuel mixture.
