runs with half choke

I have a kohler 25 hp (carb) 163 hrs. on a Vermeer chipper.....motor runs very well with half choke and spits and sputters with choke off. I have replaced plugs, fuel filter and line. ran it out of fuel and replaced with fresh gas. the carb looks very clean looking down from the top and the choke flapper is working as it should......any ideas?.....Clay

You have debris in one of your pasageways in your carb, probably the jet. Take it off, take it apart, soak it, put it back together. If I'm not mistaken, that carb is pretty close to $300.00, so hopefully yours will clean up. If you don't have an ultrasonic cleaner, I would highly suggest you take it to a shop that does and let them put it in there for you.
