Your lawn mower`s carburetor regulates the ratio of gasoline to air mixture. If the carburetor isn`t getting enough air, the mixture has a higher percentage of gasoline, which can create black exhaust smoke. It`s possible that a dirty or clogged air filter is preventing sufficient airflow into the carburetor.
Smoke After Warm Up Oil can enter the combustion chamber past the valve stem seals or pistons rings, so if this symptom persists then one of these components may be compromised. White smoke exiting the exhaust pipe after the engine has warmed is a sign that coolant is burning in the combustion chamber.
