Motor dies at Full throttle

So i have a xr50 and haven't ran it in awhile. Anyways with the choke on half way it runs fine and i can give it full throttle and it responds yet once the choke is turned off it will only idle and take slight throttle, once i open it up it just dies. I think the main jet might be clogged, unless it runs on the same main jet with or without the choke on? Could it also be something like one of the air/fuel screws? any thoughts would be appreciated
