My Peugeot speedfight 2 won't start?

Hi I have a speedfight 2 and I have recently put a new piston and barrel on it and I have also put a new fuel tap and a new choke on it now it won't start using petrol it will only start using carb cleaner. Has a good spark and good compression all lights work. When it starts using carb cleaner it will only stay running for a little while and as soon as you put revs on it dies and cuts out.
