Super C Carburetor Leaks?

I have what I think is a 1954 Farmall Super C with fast hitch that I use for light work/brushhogging around the farm. Lately it has developed a leak from the bottom vent hole when parked if the gas tank is not turned off. Its gotten to be a steady drip and will empty the gas tank in a couple of weeks, if not turned off. And when I start the tractor, there is a cloud of black smoke after turning over several revolutions and a slow start. Which clears up and runs smoothly after a minute or two. So, my guess is something wrong with either the float level or the gas needle valve operated by the float. Or the float itself is filled with gas. I have been searching the internet for clues of what kind of carburetor is on this, and what kind of parts I need and where to get them. I don't see a make of carb stamped on the body castings anywhere. There is a brass tag that is kind of damaged attached with this: 771SB
E3____
22
And a casting number on the upper section of: 0-653
Some of the letters or digits may be different as they are hard to see. I have not removed the carburetor yet since I am still using the tractor. I did find a U-Tube video of what looks like the same carburetor being worked on, but no mention of make. Looking on the web for parts, I find the Carter carburetor parts look like those used in the UTube video I looked at.

So if anyone can help me identify the potential problem and give me some recommendations for repairing it, I would sure appreciate the help?
 
So, to open up the carburetor at the very least I will need the base gasket to manifold, and the split between the two carb castings?
 
Those look to me like Carter numbers (no guarantee). Look at online vendors pictures of rebuild kits until you find a gasket that looks like yours.
 
This one looks like mine, although I have not dismantled it yet. :https://www.external_link/ABC3933-Economy-Carburetor-Kit-for-Carter-Carburetors
 
That is a carter carb and based on my recent adventures with mine they are sensitive. Guys here told me that it was either the float or something in there somewhere. I took it apart and ultrasonic cleaned it. Took out the long jet and the fitting the needle valve sets in but the small jet deep inside I couldn't get and left it before I damaged it. And that worked. Careful when you air blow that you don't blow out that drain plug! They are finicky.
 
On my Super C many years ago the needle was seeping too. IH wanted big money for small parts! I polished the needle into the seat with a drill & used toothpaste as a polishing compound. It is still ok but we always shut off the gas when parking it.
 
Does it look a little like this one?

That’s my ‘54 Super C. A few years ago I replaced the needle and float with a kit right off the hook at TSC. Very little info on the package except model and years it was supposed to work in. It worked. Maybe I got lucky? I think I put it on two times before I got the float adjusted enough to close the valve. It is not at all difficult. Hardest part is pulling the pin out of the choke rod.

Shut the gas off when you are done using it, NEVER a bad idea even if the carb has been behaving.

If the sediment bowl shutoff isn't completely closing off the fuel you can install a small brass ball valve in the gas line to reliably get the job done.

Yes, this one looks like it. Although I haven't taken it off and turned it upside down for a "same view" photograph! I will order one of the same kits and get it off and repaired. I do have some older carb soak cleaner in a gallon paint can with an included parts basket that I have had for more then a few years. I hope it still works. Thanks for the help.

The handle fell off of the "aftermarket" sediment bowl so it is hard to turn off. So, maybe I either need to install an additional ball valve as you suggested or rebuild the original one or take the valve shaft out and see if I can reattach another, better handle. Of course the original handle fell off somewhere when I was running the tractor.
