Bump it up to 3600. That's pretty much the top no load for most all Briggs.
It will run all day long at that speed, no problems.
In fact, 3600rpm is pretty much what all small engines are designed to comfortably operate at. From an old lowly little side valve push mower motor to a brand new twin OHV. Some even a bit higher!
It ain't rocket science!
