Is there anywhere on here that shows you how to rebuild a usx 20 carb?

That's the MS aluminum carb. for like 3020-4020 isn't it ?

If so use it for a door stop and get a Zenith ! Deere even had a bulletin telling you to do this.

I have rebuilt MANY carbs. and worked on mine off the 4020 several times,but still was short lived and had off idle over rich problems. They have an accelerator diaphram that sits below fuel level seems to go bad and leak and not meter right anyhow. This is the only thing I have ever give in on and followed what I was told by others and finially got a Zenith. It was worth it !

Melt that carb down for scrap.

Buy a rebuilt Zenith.

Worth every penny.
