Car died comming to a stop and would not restart. Carb is flooding

It was cold outside, and had driven maybe 3 blocks. I had the defroster on and was approaching a red light. As I slowed down, my car started to act like it was going to die, so I tried to quickly turn off the defrost, but it died anyway. It has done this multiple times in past during cold weather. But it would not restart. The previous month I kept smelling gas coming from under hood area, but could not find any fuel leak, and the exhaust smelled like it was running a little on the rich side. Pulled the air cleaner assembly off and my carb was flooded. Two hours go by. Called a shade tree mechanic I know(big mistake) and they had me try and start it. My carb was dumping a ton of gas to the point it was overflowing the primary chamber and going into the secondary one. So this guy turns my float adjusting screws all the was shut and the gas would still pour in. Am I in need of a carb replacement? Or is there some other parts I should check before going this route? I need to get my car going asap, as it's my main source of transportation to my job I've had only a couple of months. PLease help!

My car is the Accord LX 3 door hatchback 1.8L with a 3bbl Keihin carb on it. It has the 49 state emissions engine.
