What happens if you close the choke some when throttling up? If it tries to gain RPM with choke closed, problem is fuel supply. Could be float height adjustment or fuel/air mixture screw(s) not correct. Just because it is new carb does not mean it is set correct.
Have you checked the ignition electrical?

You may get more response and help from those familiar with Kohler engines if question is posted in Parts & Repairs.

Something blocking main jet. Perhaps water. Perhaps a particle.
