This is a replacement carb too. It's not on that far but the engine is definitely happier with the choke out about 1/2 inch. This is all warmed up too. I am wondering if this could be a problem with the float adjustment, governor, timing, whatever. Thanks in advance.

Three filters in your fuel system. One in the tank, one in the sediment bowl and one in the elbow at the carb as mentioned. Once mine were cleaned on my first tractor I didn't need the choke anymore. I also run 1/2 can of "Gum-Out" with every few tank fulls to keep it clean. And of course the carb is adjusted properly.

My choke was able to stay closed too until I did a carb rebuild when I found a broken choke return spring.

As the post below states, the choke should spring open when let go...

There are two possibilities it needs partial choke to run smoothly...One is in the post below...The other is possible airleaks in the carb...

How do you drive with one hand holding the choke? It is spring loaded so it goes to 'no choke' when you release the knob. Do you hold it with your knee or something? Just kidding....
Sounds to me like you have the carb and it's associated stuff all set up to work in a way not very similar to how it was designed to work. That makes figuring out what is wrong kinda tricky. If it was mine I'd free up that choke so it worked properly and then set up the carb like it's suppose to be and see what happens. In your case everything might be 'rigged' like it is coz it won't work like it's suppose to and some guys would leave well enough alone. Your call.
If you want it to work properly you need to go to square one which is:
Choke springs close and the idle screw should be near 1-turn open (CCW). Turning the screw in (CW) enriches the mix. Set it at one turn and then run it at idle and warm, turn in til the engine falters from an overly rich mixture and the back it out until the engine smooths out.
The main is CW to lean the mix. One turn open (CCW) for initial setting. Lift a heavy load, run at a governed speed and turn the screw in until the engine begins to lose power, then out til power picks up and engine smooths out.
Than it should run without any choke except just a 'bump' to start it.
Before you start messing with the carb take off the fuel line at the carb elbow and check for a 'full-pipe' flow, thats a heavy, steady stream. Make sure the screen in the carb is there and that it's clean. TSC sells new ell w/screen. Keep the old ell coz you might find a use for it on your gov or oil filter one day.
You can remove the inlet air too so the carb adjusting isn't messed up by a plugged air filter.
After you get it right then if it messes up you can follow normal troubleshooting procedures given on this board to go right to the problem, mostly.
