You must have something in the accelerator pump outlet. Most of the AFB carbs that I have done (and that's a lot) have had the needle valve.

As I remember, and it's probably been 30 years since I've done an AFB, there's one in the accelerator pump well (ball) and the needle under the discharge nozzle (#42). I used to do them all the time back in the 70s and 80s, but the demand to rebuild AFBs just went away when the cars they came on were no longer road cars. The last one I did was for a 61 Bonneville in the 90s.

I may be wrong about the ball in the pump well, you can forget details over 30 years, I'm sure of the needle under the discharge nozzle, that is clear for sure.
