just installed 305 - carb help!

[mexlokote]

i just finish installing my 305 on my 82 c10,

now im having an issue with the carburator, holley 650 double pumper

i had it on my 1963 chevy c10, but i changed to a newer one ,
this holley 650 worked great! i had it in my garage about 8 months.

when i turned my engine on for first time it started right up but then gas was coming out of the holes on top.

im new to this carburators but for what i have seen this is not normal, i did a picture of a carburator picture i found online,,,

1 and 2 arrows point where the gas is coming out of...
im guessing its flooding???
