25 HP Command CV730S-007 starts with choke but won't continue running.

I have a Kohler 25 HP Command CV730S-007 on a Great Dane 61 mower, Build Date was 05/08/2007, the engine was replaced a few years back.
The engine will start with the choke (running rough) but will die shortly after the choke is removed. It had been running ok an it just died and this is the result. I assume it is a fuel problem, so I replaced the fuel filter, checked the fuel pump and it is pumping fuel to the carburetor. Any help would be greatly appreciated.

Dirt, debris, or corrosion causing a restriction in the carburetor. Needs to be cleaned.

By cleaned, he means a complete rebuild, not just hit it with some air or carb. cleaner and expect it to work.
At least 95% of small engine issues are fuel related.
I run all my fuel through a funnel with a built in filter, add a fuel filter to the fuel line, only use non ethanal fuel and almost never have fuel issues.
At the end of the year any tool I know I will not use again until next year I drain most of the fuel, add Stabil and run it until it's out of fuel.
Never leave old fuel in the tank!
