I have s/c that if I leave the valve on it drips out of the carbutor does this mean the float is stuck or has a hole in it

Definitely the carburetor needs attention. The most likely suspect is the needle valve and seat (float valve), but it could very easily also be a defective float, or an improperly adjusted float.
If the float valve and the float are both in good condition, then you should NOT need to shut the fuel off under the tank. If the fuel DOES need to be shut off to prevent dripping when the engine is OFF, then the faulty float or float valve is going to cause an over-rich condition even when the engine IS running. Poor idling characteristics, fouled spark plugs, etc. Think about it.
I had major problems with my Super C just like what you are experiencing. I had the Carter carb in mine, and I'll bet it's the same carb. I no longer remember the numeral designation. I replaced the needle valve with a rubber tipped one, made sure that the float wasn't scraping against the side walls, and of course the float properly set. I never could adjust the jets properly, it always ran too rich. After fighting it for close to a year, I ordered a new Zenith carb, and never had another problem with it since.
I typically like to have every little thing working just right, and this will go a little against my nature... but in this case, I'm leaning towards agreeing with this answer.
If the mixture is correct, it's running smooth, and you're not having any trouble starting it, I say don't go messing with the carb. (or at least wait till a time in the year when you won't need the tractor for a while)
You're much more likely to introduce a new problem than anything else.
If you don't believe me, do a search for "I just rebuilt my carb and..."
Not that it's hard to do, it's just that so many little p-i-t-a problems can occur.
Use it as an excuse to turn the gas off everytime you're done, which is what you should be doing anyway, and there's no downside.

My 1953 Super C had a Carter UT carb and after several attempts to make it work with various rebuilds I obtained a NOS Zenith like Dave_Id who posted below and I have experienced the same success for the past several years, Hal.

Check the link. This is how I tested my carburetor. The float, needle and seat are fully functional this way, while being able to see the parts and the process.
You may have a leak between the thread of the seat and the carburetor body, which may manifest itself as a leaking needle to the innocent observer.
(You can do this while the carburetor is onthe tractor.)
