Fully charge your battery first. Just because it is new doesn't mean it has a full charge.

If you have tried starting it and it won't run, pull the spark plug and see if it's wet with unburnt fuel (indicates an ignition problem). Drain the fuel and top it up with fresh fuel if it has been sitting for a long time. Make sure the air filter is clean. To do a diagnostic start, take the air filter and moisten it with fresh clean fuel (enough fuel so it's not dripping out everywhere), reinstall the primed filter and attempt to start it. When it starts, open the throttle up and run it hard. The engine will struggle to pull fuel but with some luck it will then run normally. If this doesn't work first try, repeat the process. It may have water contaminated fuel in the lines and won't clear immediately. Good luck.
