How to fix Yamaha EF6600DE when engine won’t start?
- DDeanna BishopAug 1, 2025
If your Yamaha Generator won't start, it could be due to several reasons: * No fuel is reaching the combustion chamber, so you should supply fuel. * The fuel cock lever might not be “ON”, set it to “ON”. * A clogged fuel line could be the culprit, in which case you should clean it. * There might be foreign matter in the fuel cock, so clean the fuel cock. * The carburetor might be clogged, so you should clean the carburetor. * The oil level might be low, so add engine oil. * Ensure the engine switch is set to “ON”. * The spark plug might be dirty with carbon or wet, so remove the carbon or wipe the spark plug dry. * If these steps don't resolve the issue, there may be a faulty ignition system, and you should consult a Yamaha dealer.
