carb leaking gas, what did I do wrong?

[jason78613]

Got a rebuilt Stromberg 81 carb from Uncle max, and a new fuel pump from Charlie NY for my '38 60hp. Car is smooth at idle but sputtering when I accelerate hard. After extensively reading through the forum, figured I'd check the float level...

I removed the screws around the top of the carb and lifted the top, cranked the engine a bit and it filled up the float bowl just fine... I'm not an expert, but everything looked right based on reading.

I put the top back on, tried to start the car, but it wasn't starting at all, and after a bit of cranking, quite a bit of gas seeped out of the hole where the accelerator pump goes into the top of the float bowl. (see attached picture) I removed the top again and checked the accelerator pump rod and the felt washer is there, along with the metal washer, springs, etc, but not sure if I'm missing something else?

Did I do something wrong? What typically prevents gas from coming out of that hole? what is causing gas to come out of that hole now?

I'm a noob, go easy on me.
