Ruixing carb problems

I have an S/A Ruixing carb that when I came off the track the engine shut off and will not crank. I have taken it apart twice and cleaned all the fuel passages. It will crank then shut off. If you crank it and hold the throttle open it will Rev up but not idle at all, it shuts off. This one has me perplexed. Any ideas?
