It's pretty common for the factory settings to be way off. It will run if my recomendation is to rich
but not if it's to leen. If you have someone to help hold the plane , try starting it at 1/2 throttle or more.
If it's a low end problem it will run at more than half throttle because the low end wont effect it.
DON'T DO THIS unless you have an electric starter. Hand starting one at a high throttle settings can cost you
a finger.
