'85 1.8L dual carb gas spewing out air intake

I took the air box off the back, started it up, gave it some gas and gas came rushing out the small hole near the top right (when looking forward) and the brass looking splitter where it looks like two vacuum style hoses attach to.
Just taking a guess as to what is occurring: the seats for the float stops are worn out and gas makes it past the gas stops regardless of float position.
Consequently, gas is also making it into the combustion chamber not atomized and at much larger rates than normal, so the engine is choking.

If I am correct, are there any recommended guides to follow when dissassembling and reassembling the carb set? I have plenty of experience working on carbs off of small 2 stroke motorcycles, but nothing bigger.

If I am incorrect to what is causing the problem, does anyone have experience with this issue and could lead me in the right direction?

Thanks ahead of time.

I have now uploaded a video to YouTube to better show exactly what is happening.
