assuming that you are working on a briggs engine? regardless of make what the problem is that the needle and seat inside the carb is not sealing off the fuel flow from the fuel pump/fuel tank or both......gravity feed fuel systems are the worst about flooding, the only fix will be a carburetor repair with needle and seat replacement

You have a solinoid on the carburator that is not shut the fuel off when the motor is not running. you have to replace it or it will fill your crankcase and cylinder with gas a ruin your motor.
CHECK AND SEE IF YOUR OIL IS WAY TOO FULL.

My name is Dane and I'm going to help you with this. I need you to do a couple of steps for me, and one involves using a voltmeter. You can pick up a cheap one at a hardware store or auto parts store. They will even show you how to use it if you need them too. It will come in very handy around the house and well worth the $15.00 you will have to pay for it. Put your battery on a charger while you get the meter so it will be fully charged later. When the battery is charged, remove the charger.
I want you to set the meter up for Volts DC and (With the engine OFF) place the red lead on your battery positive terminal and black lead on the battery negative terminal. If your battery is charged ok, it should be around 12 volts.
Now, I want you to start your tractor, and check the voltage again with the engine running. Do it the same way you did with the engine off. If you are getting around 13.5 - 15V, your mower is charging and you probably have a bad battery. Check your terminals and make sure they're clean and tight. If you got the same voltage with the engine on as you did with the engine off, make sure the electrical connectors coming out from under the shroud of your engine are all connected. I've been doing this for a while now and I've never had a stator go bad yet. Not saying they won't, but it's very rare. To change the stator, which is actually like a car alternator, you have to remove the top cover of your engine and pull the flywheel off. It's normally bolted to the top of the engine block under the flywheel. If you come back and tell me the stator's bad, I'll tell you how to do it. But for now, I think you'll have enough information to get back running again.
Just a note. Those stores which use the resistance type battery testers. The ones that Glow red when they test your battery. They can't really properly test your battery unless your battery is fully charged to begin with. Amazing how much money they make on that little "FREE" test.
Ok, if you have any more problems with this, just add a comment on the bottom of this post. I hope I've helped! Thank you! Dane

Hi and welcome to FixYa, I am Kelly. This sounds like you have a bad cable between either the battery and the start solenoid or between the solenoid and the starter. Also look at your battery gound connection cable from the battery to the chassis. Both the - & + cables vibrate a lot from normal mower use. The cables fail most of the time at the terminals. Often most of the strands are broken right at the connector / teminal ends and the cable can not carry the amperage needed to run the starter. Additionally... make sure there is a good ground from the engine to the negative post on the battery. Usually this is done simply though the engine mount bolts and the common ground it the negative battery lead and terminals.
One more thing to do is remove the spark plugs..... If there was a failure of the carb float for some reason the carb can fill the cylinder and the engine crank case with fuel. If this happens the starter will engage but will not turn the engine because the fuel makes a hydraulic lock in the cylinder.(s) You must remove the spark plugs or you will bend the connecting rods. Check the engine oil servicing also. If the carb float has a problem the crankcase may be completely filled with fuel.
Just from reading your sympton, you should be looking at your battery cables and the solenoid terminals for the starter.
If you do not find anything respond here and I will research further... and look up the service manual.
Thanks for choosing FixYa,
