I just replaced my carb with a rebuilt unit from this website. I thought I'd get rid of the sediment bowl, so I replaced it with 3/8 pipe thread nipple into a 3/8 ball valve shutoff with an inline filter behind that, and rubber line into the carb. If I open the ball valve, the tractor will start, but eventually dies out and then a bunch of gasbpours out the bottom. Is my 3/8 line plus inline filter too much fuel flow for the carb? If I barely open the ball valve to turn on the gas, the tractor seems to run fine, but still doesn't seem like it runs as good as it should. What do you guys think?

Sediment bowl had a raised end above the threads to help lessen the chances of dirt or rust that falls to the bottom of the tank from flowing to the carburetor. You eliminated that with just a plain 3/8 fitting. Unless you have a nice clean tank, could be depending on the filter that crap already made it to the carburetor needle and seat and causing the problem.
If everything is clean I would consider returning the carburetor. Probably won't take it back if you work on it.
Unless you have a modified pulling engine the original type strainer is good to go.

They are super simple.Just loosen the screws and lift apart.. look for a float dragging on the side;a hole in the float;the pin holding the float come loose;the float set too high. Something is not letting the needle/seat valve close completely or holding it open.If you have to,buy an 'economy' carb kit. It will have basic instructions,and gaskets.

Look for rub marks on the carb bowl, where the float, might have been been touching,they will be very light,or maybe the float pin has walked out, to one side, that has happen to me. if your careful, you might be able to use the same gaskets over!!! Treat that float very carefully !

kind of a unwritten 'gotcha' rule,
if you have to mess with gas lines for any reason, a small
bit of debris will come loose and hang up your needle.
clean it and you'll be fine.

You can try this first, may be a problem since you are not familiar with doing it.
To check the float operation with carburetor mounted. Remove the drain plug, use a spray can plastic extension up through drain hole. Place end under the float opposite the needle valve area. Gently move the float up and down angling the plastic to each side a little to move what play the float and pin has toward each wall.
You can feel it if they drag the sides or if there's a hinge problem. Also with help you can gently hold the needle and seat closed, turn fuel on a little and see if fuel leaks down on your hand. If so the needle and seat is not sealing, gasket on seat leaking or a damaged, leaking throttle body casting.

Send it back. Do NOT work on it yourself for any reason. Just send it back. There is NO warranty if the carburetor has been tampered with.

theres a stop tang on the float that sets on the needle seat housing. when carb is upside down, the float should appear level, and then right side up, the float just drop just enuff to open the needle. it may drop about a quarter inch. if yt says send it back, then you should send it back but to me, id tear into it n fix it. and yes, you could have a dirty tank since you put the eliminator kit on. check your gas line fitting at the carb, see if anything is in it. if there is, then you got dirt in it. good luck.

Agree with RustyFarmall, send it back. At a minimum, call YT and explain the situation. Since is had gas in it, they may not take it back. Ben a few complaints about YTs service on here lately.
You voided any carb warrantee when you removed the device (sediment bowl) that insures the carb won't get contaminated with debris from the tank. Why did you remove the sediment bowl anyway?.
What happened to the original/old carb?
Rubber lines don't work well in an engine fire.
