carburetor tuning fora jet ski

i have a 88' kawasaki 650sx i just put a new carb on and it is all hooked up, but when i hit the start button the engine cranks and no fuel goes to the carb. im pretty sure the fuel pump works.

this carb is about as simple as they get, choke, idle, and two screws for tuning.

can anyone helpme get this thing going
