The smaller Farmalls I have could have a Zenith or a Marvel Schebler carb on them and maybe a Carter carb. Were any of those carbs considered better than the rest? When you price new carbs seems like a new Zenith is way more expensive than anything else but is it any better.

Just one man's humble opinion, but Marvel makes a lot of carbs for aircraft. The specs for aircraft systems are very demanding. I have a 1957 plane with a MS carb on it and it has worked flawlessly for +60 years with nominal maint.

I don't know about new. Both on the tractors I have worked on, and owned, the Zenith and MS have performed equally.

Haven't heard anything bad about any of those three.
The only really bad tractor carb I have experienced (and so have others), was a Holley.
But buying new, at least the MS, you will get an aluminum knock off.
If your original is broken, or missing, I would go for a rebuilt original over an aftermarket fit-all.

I have had bad experiences with both Carter on IH and Marvel Schebler on IH and John Deere. That aluminum carb on a 4010 had way too many sore spots but then the Zenith was not so great on those tractors either.
It was one of the things that even the deep down green boys in the shop cussed out.
IH came with a Zenith service only replacement carb on the Farmall 460 and it made a whole new engine out of those spitting and sputtering so and so.
