Black smoke from the exhaust usually indicates a rich fuel mixture. Start by checking the air filter to ensure it's not clogged, as this can restrict airflow and cause the engine to run rich. If the air filter is clean, it might be worth inspecting the fuel injectors for any leaks or malfunctions. Let me know how it goes or if you have any further questions!
