choke/throttle fuel run problem dyt 4000

I have a Kohler 26hp v-twin Pro w/nikki carb. It runs smoothly at half throttle w/ about 30% choke not engaged. Dies instantly when engaged. I have drained,flushed & refulled. Rebuilt carb & accelerator pump & replaced fuel pump. Any advice would be greatly appreciated.

One would be led to think that you are not getting enough fuel to or through the carburetor. Feed the float bowl via a gravity tank, and if that works, your pump or lines are dysfunctional. When running on a gravity feed, the pump and fuel tank should be pumping the tank empty at a pretty quick rate, so have a catch-can ready just in case the problem is within the carb.
Doing that will at least point to the carb or fuel delivery system.
