kohler power washer won't run off choke

Shellx again. Have a Kohler Courage XT 7 on a Husky power washer. It didn't run off choke. Went through carb thoroughly with carb cleaner and air pressure. Now if I slowly open the choke it will run till I use the wand then I dies. If I hold the governor rod (mechanical) and use the wand it tries to run, release the wand then try the wand again without holding throttle it dies. Only jet I didn't clean was behind the welsh plug. What am I missing? Also pulled muffler- no obstructions. The unit is only a couple years old.
