I have a Honda eg5000 generator. The other day I was running it, shut down for lunch, came back, added fuel for the afternoon and checked the oil. Needed some, added some. Started the genset and oil puked out the fill hole where I had left the oil fill cap off. Shut it down as fast as humanly possible. Added a bit more needed oil, put cap on, started genset, Fired right up but generator is not putting out power. All circuits and fuses are good. Any ideas will be appreciated.
