I think my carb on my Super C is plugged up, it wont run without the choke half way out, and spits and sputters and sometimes dies. The tank looks clean from what I can see though, so I was going to swap the carb and fuel line off of my C onto the Super C to see if that's what my issue is, but I'm not at the farm to compare them. Thanks!

Yes, they will bolt up. I have a very early C with Zenith carb that
has a smaller venturi than the later C's and Super's. I did put that
small venturi C carb on a Super C and it has more than enough
power. It will lose traction before it stalls. I replaced a Carter carb
that was junk. Thinking that it wasn't "right"I later put a Zenith
Carb off of a 240 on the SC. Couldn't tell any difference. Runs
great and will spin the wheels before it stalls.

Yes, they can be bolted up. I have troubleshooted carb issues myself swapping carbs between my A, Super A, and C. The differences have already been mentioned on jets and such (I actully have a kero carb on my Super A right now and have yet to run out of power plowing the heavy abundant NY snow). Good luck!
The manifold has a crack where the exhaust pipe goes into it, but I wouldn't think that would cause it, being that the pressure is all external at that point. Here's a quick crappy cell phone video of what it does. Runs...dies..yank on the choke, comes back to life, breaks up, push the choke back in and repeat in 10 seconds. Sometimes it will run for a few minutes with the choke all the way in, other times it has to be pulled half way out to stay running. The weird thing is, if you let it die, and fire it back up, it will run fine for 10 mins then start acting up again. I don't think it's electrical, because everything with the electrical system is new, and pulling the choke keeps it running.

ow long do you wait between die and fire back up?
My guess is a fuel flow restriction but not at the main jet. Maybe you have a restriction between the tank and the carb bowl. How about junk in the fuel tank that floats over the outlet?
However long it takes to climb off, walk to the front, and restart it with the hand crank. Not long, about 30-45 seconds. It does have an inline fuel filter between the carb inlet and sediment bowl, I suppose it could be clogged. The inside of the tank looks fairly clean though.

The vent in the fuel tank cap sometimes get plugged and will cause those symptoms. Kind of a far shot, but it bears looking into.

hat is probably the problem.
If the tractor has been setting up for a while it is not out of the question that it will run rough for a while especially with the gasoline we get now. Ours always did for about the first fuel tank after a long rest. You may have to clean the fuel line, drain the carburetor, and clean the sediment bowl several times to get it to run just right. Try this before taring into the carb. It may be the old gasoline. Some of those fuel additives that dissolve the water may also help.
Well I swapped the new manifold off my C onto the Super C, as well as the carb, and fuel line. Now it won't run for manure. Sounds like it's firing on 1 cylinder. The C runs perfect with this setup on it, so I don't know what the deal is. Got dark quick, and cold, so I came inside for the night.
