I purchased a Thor Quantum 2019 last year, recently I had problems with starting QG4000 spec R gas generator. When I inspected I found a nest on top of the generator, probably chipmunk, I have a problem with them here.

Of course this concerned me, but to rule everything out, since I hadn't done any maintenance yet, I replaced everything, spark plug, oil (15W30), fuel filter, and air filter. Plug is gapped correctly, and I'm in WI that's why I chose that oil viscosity. I started it after changing everything, but the oil, and it kicked up right away, but ran a bit rough at first. Then I changed the warm oil out with the 15W30 and ran it again for a while, again started out rough, but smoothed out.

This afternoon, I'm back to the same problem. I get 3 flashes, 3 flashes, 3 flashes, etc, which seems to be the most general and least informative code. One thing I noticed with the old plug, it was extremely black, with either an oily or gas substance on it, I tend to think gas, which makes me think maybe the carburetor is too rich? Any thoughts would be appreciated.
