Default fuel doesnt prime

i have beed trying to get my 3.3 to start for some time now, and the fuel does not prime! it will prime when i disconnect the fuel line from the carb thought, but when i put the tubing back on... it does not prime! i cleaned the carb w/ some brake cleaner and let that dry. i put it back and it still dont work!?!? i think there is an air leak in the engine somewhere

what is wrong???!!

When I had that problem it was the exhaust pipe leaking air, at that bit of rubber tube between the pipe and header.

check your pipe connection, fuel line, the pressure line from the pipe to the tank, and any exaust obstructions that could be stopping the airflow

Have you tried getting it to start when you manually prime it to the carb? Use the method of blowing into your pipe fuel line.
