I believe this TO20 to be a 1949. What carb is this? I need to order a kit.

Take it off and clean exterior. Should be numbers on it.

I have a "franken Fergy", TO20 but TO30 engine. When I rebuilt carb numbers showed it was the TO20 carb.
 
The original TO-20 carburetor was a M.S. TSX-361. But that carburetor that you took a photo of in your earlier post is nothing like I've seen before.

You might want to take yours apart and check it out. It might be just some junk that got into the needle and seat area.

After looking at photo in the link appears to be a Zenith carb. I never worked on those.

I hope this link is OK to post? Nope, link to another site a no go.

The link has Marvel and Zenith carb repair manual. Zenith section covers 61 and 161 carbs and tells a little about serial numbers and carb kits. Should be a metal plate riveted to top of float bowl. Number near rivet is Zenith number, other one is vehicle manufacturers number.

It also states there are "basic kits" for most Zenith carbs, and supplemental kits for rebuilds.

Not sure how to send personal emails/messages to members here? If so I could forward you the link.

Edit: Checked site here. Lists kits for Zenith carbs.

Edit: cross reference for tsx361 is Zenith #12522

Mad Farmer, that is good info. I've heard about Zenith carburetors many times, but have never seen one.
My TO-20 has a Carter UT carburetor on it. I'm guessing that the UT stands for Universal Tractor.
