    Why does my EarthQuake Tiller engine lack power?

      Rebecca MillerSep 13, 2025
      If your EarthQuake Tiller engine misses or lacks power, the gas tank might be clogged, so remove and clean it. The air filter could also be clogged, so clean or replace it. If these steps don't solve the problem, the carburetor may be out of adjustment or bad, and you should call the factory. Additionally, the spark plug might be wet, faulty, or improperly gapped, so clean, replace, or gap it.
