I'd run all the needles in and run it until the fuel burns off.
Next put a little fuel down the throat and see if you can get it to run on prime.
If successful, I'd open both needles 1/2 turn out and repeat. If it try to run and dies, open the low needle another 1/4 turn and see if you can get it to idle.
If it floods, the lever on the diaphragm is too high.
