Fuel leaking from Air cleaner (Ear?)

Hello everyone, this is my first post here. I'll be picking up my 1988 Vulcan750 Saturday morning and am very excited, its in really good shape the only issue is that one cylinder floods if ran for a while and fuel is leaking out of the air cleaner housing or Ear I think you guys call them. The seller tells me that it just needs the carbs cleaned, unfortunatly I know nothing about carburetors. I searched and found the awesome disassembly/ assembly video and I think I can handle cleaning them myself. I just wanted to know if this sounds like something that needs to be cleaned, or something that may be out of adjustment and harder to determine. If this is a dumb question I'm sorry I really did search. I'm just clueless when it comes to carbs. Thanks

If it's a float that is stuck, you could try to pull out the drain screw and shoot some carb cleaner into it and tap on it a few times with a screwdriver handle. It's worth a try....

Fuel tap = petcock. Make sure the petcock isn't leaking gas when the engine isn't running. Pull the two fuel lines (the outer ones) and see if fuel continues to come out of either side. If it does, the petcock should be rebuilt or replaced.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

And just incase you're still unclear, it is located on the left side, near the back of the gas tank. pointing down is "on"

Just a little update, after about two and a half angry hours I finally got the carbs out. Holy hell you guys weren't kidding about it being a tight fit, I have a lot of respect for those that have done it themselves. I'm going to let them sit outside until tomorrow to air out a bit before I pull them apart. I think in the mean time I'll be looking into an air box delete...
