Generator emits excessive black smoke from the exhaust during operation.

How to Fix / Troubleshooting

Safety first: Operate the generator outdoors or in a well-ventilated area only. Avoid inhaling exhaust.

Check choke position: Ensure the choke is fully open after warm-up. On automatic choke models, verify the linkage moves freely.
Inspect air filter: Remove the air filter element and check for heavy dirt or oil saturation. Clean or replace as needed.
Check for fuel flooding: If fuel is dripping from the carburetor, the float or needle valve may be stuck. Lightly tap the carburetor bowl with a non-metallic tool to free it.

Persistent black smoke may require carburetor cleaning or adjustment by a technician.
