Generac gardian model:005885-0 running rough
I recently purchased a 17kw standby and on initial start up it ran fine but every weekly exercise since, it runs very rough and is not up to the full rpms with a srong unspent gas odor. Please help.

Most likely the problem is within the air box itself. When in quiet test mode the controller calls for minimum actuator position and the choke plate closes to accommodate air/fuel ratio. There have been issues with manufacturing of air boxes. The solution will be to replace the air box or simply disable the quiet test mode.
The 17 & 20k units have a quiet test mode, sounds like the typical symptoms of that. It is completely normal but if you want you can set the generator to not do the quiet test by selecting "no'' in the program when it asks about the quiet test Yes/ No on that page.
Check the spark plugs, ignition coil etc and try to start it manually.
