John Deere 1010 Carb Issue?

Previous post indicated had trouble getting engine to stay running after started. After changing 10 year old coil that read open when hot, repairing battery ground cable, and cleaning fuel line from tank to carb and finding pieces of thread tape plugging up stuff, we now have sputter and run sort of. Also found that the filter that is supposed to be at the inlet fuel elbow is missing. So, it now takes full choke, with throttle set at idle, to get it to start running. Set choke to half throttle, then it runs about a minute, then seems to get flooded out and stops. Also, when trying to move throttle up from idle, has the same effect on running. Lastly, removing fuel cap makes no difference. I tend to think that carb was set to run with the reduced fuel flow, and needs to be reset in some way, but I do not know what I should adjust, if anything. Looking for additional information or suggestions as to what to do or try next.
 
Without the tractor running have you verified fuel flow out of the drain plug on the bottom of the carb now that you have cleaned somethings? You could have dislodged more foreign material and it could be causing your float to stick open. If it is truly flooding out do you get gas dripping out of the carb? Remove the hose to the air cleaner pipe when trying to start/run and see what happens. Also, have you checked that air cleaner pipe or system for a blockage such as a mouse nest or overfull oil bath bowl?
 
Yes, I actually had to clean out the drain holes in the bottom of the carb, to get the drain to function. I am getting a nice stream out when I pulled the drain plug out after putting everything back together. Is there a way to test what that should be, like fills a pint in blah, blah time, or something?
There is not a flood at the carb intake, but it is wet. I was running it this time without the air cleaner hooked up, for that reason, to prove or disprove there was an issue with that. I should have mentioned that in the original post. I have checked the oil bath level, and it is ok. Before when it was running, before all the foreign material showed up, I could feel a good suction on the air breather.
 
So my next thought is if you didn't have a screen at the carb, and had a plugged drain on the carb that you may have a piece of junk stuck in the carb not letting the float close all the way allowing the tractor to flood. Is there a screen in he fuel bowl? When you take off the bowl there should be a cork gasket and a piece of basically window screen. That's not the issue here but just another spot to have some fuel filtering for the future.

I am not an expert on carbs at all and send mine to other people to be rebuilt. That being said you could take the carb off the tractor and take the bowl portion off by removing the 4 flat head screws. You can then see if there is a bunch of junk in there and blow it out with some light compressed air. A good cleaning might get the float to unstick. It should move freely. Maybe someone else can chime in on how the float should be set. They can be easily bent into, or out of, proper alignment not closing the fuel valve all the way.
 
Hotflashjr, thanks for your comments, I do appreciate all the help I can get.
So basically I started at the carb and worked my way back to the fuel tank the first time, which is where I found all the thread tape pieces in the needle valve for the tank shut-off. I then got flow on the line going into the carb, but still no fire, as I stated. After that posting, I learned about the screen behind the inlet elbow, so I then took the carb off, and found the carb screen missing. With that information, I removed the 4 screws like you stated, found the bowl drain plugged up, but I did not see any evidence of any debris anywhere else. The float seemed free. I put all the adjustment screws back in the same place I found them, hence why I wondered if maybe they are not adjusted right, now that I have good flow. I ordered a service manual after the first go round, but it has not arrived yet. There was a screen and a rubber gasket on the sediment bowl, under the tank. I have cleaned this screen and put it back in. I plan to take the carb off again, as soon as I build a bridge to reach the tractor, with all the rain we got yesterday, luckily it stopped on a high spot, and is now on an island, and check the float out in greater detail, and see if I see anything else.
