My brand new Generac 20K Guardian has been exhibiting some rough running during its weekly exercise. It is running on CNG. Proper pressure is verified. It is running in quiet mode, 2400 rpm. I can smell unburnt CNG from 20 feet away.
The installer returned and ran it in normal power mode, 3600 rpm and it seemed much smoother. Seems like the automatic choke is the problem. A factory tech is scheduled to eval and repair/adjust. Any ideas?
