Help with a Mariner 1996 115hp

[oneway]

Hi guys. I purchased a 1996 Sea Pro with a 1996 Mariner 115 two stoke carbureted. My question is I noticed when I run the engine and then shut it off and then raise it I get a decent amount of fuel coming out of the attenuator plate. So I opened it up and it seems like the carb on the bottom we'll call it #1 and #3 gas is coming out of it. #2 and #4 there seems like nothing coming out or very little. I did not put the boat in the water yet I'd like to take care of as many little issues as I can before hitting the water. Also the idle seems alittle high it around the 1100-1200 mark I didn't adjust the idle screw for that yet. A starting point for this problem would be greatly appreciated.

Thank you
Anthony
