I have a MF 135, 3 cylinder gas (1971-ish), with a broken carburetor mounting flange. I have seen a wide range of carbs and prices. What is the correct replacement carb for this tractor and best place to buy?
Thanks

Here is the part numbers for the Perkins engine in the 135 from AGCO' s web site.
I don't know what the difference is if any with the suffixed letter.
A search of each part number brought me to the same replacenent carbs.
I like buying from All States Ag for used rebuilt and new parts for these old tractors.
1517099M93(A) CARBURETOR ASSEMBLY (ZENITH #013338F)
1517099M92(B) CARBURETOR ASSEMBLY (ZENITH #013338E)
1517099M91(B) CARBURETOR ASSEMBLY (ZENITH #013338)

There was also a Continental 4 cylinder engine used in older models.It used a Marvel Schebler TSX882

Some carbs often have a tag attached to it with an identifying number.

I have seen replacement carbs for the MF135 ranging from $35 all the way up to $350+. That is a very wide range. Are there that much differences between them? They all claim the same part number and application. Any differences between Zenith and Marvel?

I would probably go as close to whats on it as i could. That way you would have some interchangeable parts from the old one, in you ever needed them. If a Marvel was on it I would get the Marvel. If a Zenith was on it, I would get that.

Thats what I'd do. Spare parts are sooner or later can be a plus.

Project update
Carb is a Zenith with 2-3/4” bolt spacing. So, Marvel carb won’t fit.
After thinking it over, I decided to try a repair.
I cut and bent two nails and placed them in recesses in the casting flange across the crack. After cleaning the casting, I glued the parts together and filled in the recesses with JB Weld. Then bolted the parts to a flat plate to cure. Once cured, filed the flange flat.
