Possible Causes

Loose engine mounts, worn connecting rod bearings, detonation from incorrect fuel or timing, damaged muffler or exhaust leak

How to Fix / Troubleshooting

Safety first: Turn controller to OFF, open main AC breaker, and allow the engine to cool before touching any components.

  • Inspect engine mounts: Check that all engine mounting bolts to the base frame are tight and that rubber isolators are not torn.
  • Check exhaust system: Look for cracks in the muffler, loose exhaust manifold bolts, or missing gaskets causing loud exhaust leaks.
  • Fuel quality: Ensure the correct fuel type is being used and that gas supply pressure is within specification to avoid detonation.

Persistent knocking or metallic noises may indicate internal engine damage and should be evaluated by a professional.
