Hi, bought an xt about a week and a hlaf ago been fine, up until yesterday. 
went out saturday night was running fine, came to it sunday morning and had a wee problem. 
The bike starts and idles fine, however upon any application of the throttle the engine cuts out. 
the other strange thing is that when i pull the choke to the fully in position, the bike can be revved, but only only a half turn until it cuts out again. 
any ideas as to what it could be?? 
any help would be greatly appreciated. 
Andy
