  • Zenith Carberator
  • My 1974 Ford 3000 has a Zenith on it. 13914. Started leaking gas. Noticed it has a crack in it. The tag on the carb says 13914A and has some other numbers. I've found a replacement that is 13914B. Does anyone know what the A and B mean. Is there a difference. Website says that this Carb 13914B fits Ford 3000 1974. I can't find one with the A. Prices range from $600 to $220. Some just call it the 13914. All of them look just like mime from the picture. Any help would be appreciated.

  • I found a Zenith application guide when researching the Holley on my '71 Ford 3000. I'll paste the two Ford Tractor pages below. Hopefully they will be printable/legible. Looks like the 13914 is the correct carb and this does not mention "A" or "B". If I remember right, the choke and governor linkage was different on the earlier 2000 3000 etc. so that may explain why those years have a different carb number. After seeing several references bashing the original Holley, I got stubborn and decided to stay with the original carb. After a good cleaning and kit the Holley looked good and seemed functional. I also reconnected the original vacuum connection to the distributor. Those often get disconnected by people who don't know how the system was supposed to work. I had zero trouble adjusting the Holley and it ran so well that tractor turned out to be much more than I needed or was comfortable trying to run a cutter on wooded trails. Any clean carb will run better than any dirty or botched rebuild, which is what most people are comparing when they make a switch.

  • Ok thanks for the info. I would just as soon it had the Holley on it. I didn't switch it but it came that way when I got it. The only thing that is adjust able on the Zenith is the Idle air mixture. The main jet is fixed. I'd just clean it up and rebuild it but the crack is not repairable. Gas just runs out of it very slow. Took a good look to find it. I'm going to order the one at Yesterdays Tractors and hope for the best. If I could I'd get a Holley for it but I'm sure that the linkage would be different. Maybe I'm wrong on that. Just an assumption that those would be changed.

  • The Zenith carbs were supposed to be a direct replacement that bolted right on and hooked to the same linkage. If the linkage does not match up it is probably the wrong carb and it may be difficult to get it to work right with the governor/choke/throttle. Many of the less expensive replacement carbs are "zenith style" or "Holley replacement". The build quality on those unbranded replacements is often pretty bad.

  • The linkage and everything on mine with the Zenith was fine. All matched up. I looked at some Holley pictures online and they looked different as to the linkage hookup. Might not have been. My zenith has the fuel inlet coming from the side or on the engine side. Some of the Zenith it goes to the front of the carb. I called Yesterdays Tractor and talked to a guy. He looked it up and mine is the 13914A. It is just called 13914. Yes it's confusing. Anyway I spent big on this one. The other one that was cheaper wouldn't fit he said. I could see why after looking at it closer.
