I think Brandon is right, try the choke and make sure your carb is really clean. Also, when you clean the carb (like it says in freds guide, carb cleaner and compressed air) make sure you install an inline fuel filter. If you dont, its possible that your clean carb will just get clogged again as soon as gas goes back into it. On my ciaos, I set the idle by screwing the idle screw all the way in, then let it out 1 1/2 turns. Other things to make sure you do: make sure your airbox is on tight, and make sure the bolt on the top that secures the carb is tight. Use a new spark plug, fresh gas, and make sure your mixture is correct. All of these things contribute to a properly running machine. It sounds like you are real close, keep at it and good luck!
