Is it possible my valves need to be loose

I've got a 03 300EX and every since I adjusted the valves, it sputters and dies at WOT. Ive since cleaned the carb at least 3x trying to get it right and it hasn't made a difference. Im thinking about just setting the valve out of spec again. Any advise?

Is it ever necessary to change jet size or anything else after adjusting valves?
So the issue with it dying at WOT seems to have been fixed by moving the clip on the needle all the way to the bottom. Apparently it just needed more fuel after the adjustment. Thanks for all the advise fellas
