Help! Brand new TaoTao 150 CC scooter won't start!

[Tleeves]

I have a brand new scooter here that sat for a while and now will not start. Supposed to be trading it today for a boat so I really need to get it running. What I've tried so Far is a new carburetor and a new battery. It's turning over but not starting. My son got it running yesterday and went around the block but it stalled any couldn't get it started again.

Can anybody give me some other suggestions to try?
