94 carb leak at accelerator pump shaft

[Hoodooman]

Hi,
I just rebuilt my original 94 carb which leaked EVERYWHERE. Now, it leaks at the accelerator pump shaft. I set the float to 1 - 11/32. I'm also having trouble with weepage at the bowl drain plugs sometimes. The fiber washers wouldnt seal at all so I used viton o ring seals which totally sealed one plug, and 99% sealed the other.

First timer here with flatheads. How can I seal this thing up?

Secondarily, can I adapt a 2bbl, maybe a webber? I put one on a 54 chev 6 banger once and it worked really well. Not worried at all about originality, just want the car to run well and not leak.

Thanks
