speedfight 2 starts then cuts out

hi guys ,
my friend has a speedfight 2 , it starts for aabout a min and then cuts out , the fuel gose into the carb and the fule filter and after it starts no more fuel is going down the fuel line into the filter and then into the cab dose anyone no what the problem could be or has any suggestions what it could be .

 

well assuming its not getting fuel though, id check for blocks in the pipes and filter to make sure youre getting a good unrestricted flow of fuel. if thats fine id try adjusting the float height of the carb (presuming you can adjust it)
