Possible Causes
Choke stuck closed, Over‑rich carburetor setting, Clogged air filter, Float needle stuck open causing flooding
How to Fix / Troubleshooting
Safety first: Operate in a well‑ventilated outdoor area. Avoid inhaling exhaust fumes.
- Check choke: Ensure the choke lever moves fully to the RUN position once the engine is warm.
- Inspect air filter: Clean or replace a dirty Einhell air filter element.
- Check carburetor float: Remove the carburetor bowl and verify the float moves freely and the needle valve seats properly. Clean or replace if sticking.
- Adjust mixture (if adjustable): Follow the Einhell manual to set the idle and main mixture screws to factory baseline.
Persistent black smoke can foul the spark plug and should be corrected promptly.
