When you used the 2 stroke fuel it has oil in it you need to drain the tank, and fill it with fresh gas. Then remove the spark plug to see if it is fouled,if it is replace it. Then you need to remove the air cleaner and while you are trying to start the engine spray some carburetor cleaner in the opening, it should help it start once it starts let it run  for a while to get the carb/piston/cylinder cleaned.
