Are you following the starting instructions in the manual? Choke closed, throttle open, ignition off, flip the prop 4 times to prime. Throttle to idle, choke still closed, ignition on, flip it again, it should pop and die on the 2nd or 3rd flip, open the choke, flip again and off it should go!

Yes fuel goes into the black, 90 degree fitting that is close to the throttle arm. Don't forget that the ignition will turn itself off automatically after 90 seconds if it does not see the prop moving. If you turn the ignition on an then for some reason spend 90 seconds fiddling with your TX or something you have to turn the ignition off and back on again.
