On most mopeds, you usually need to turn everything on, put the moped on the kick stand, and pedal until you have momentum going, and then turn on the choke and press on the clutch... Sometimes you have to continue pedalling it should catch on, you may have to turn choke on and off several times to help it get going. Also the throttle.
Personally, I think it's easier to just get on the moped and pedal it while standing up and enagage choke, then the clutch. As soon as it starts, let go off the clutch.
Best of luck
