  • TSX 251 carb?
  • I find info on 33 & 241 carbs but not the 251. Rebuilt with a kit for a 241.
    Was this 251 carb ment to be used on a 1950 8N? Can't seem to get it to idle good or accelerate without a hesitation. I can adjust idle with the power screw, downward screw.
    Any info out there some where in cyberland I can scour throuh? Rusty

  • "I can adjust idle with the power screw,"
    If so, it ain't idling. If the power screw does anything, it's turning faster than idle and running on the main mixture.

    These engines don't accelerate without hesitation. There is no accelerator pump to compensate for the throttle being opened quickly. Properly tuned, the engine will idle with a mixture that is almost too rich. That borderline too rich idle setting allows the engine RPM to increase smoothly as the hand throttle is opened at a normal rate. Yank the throttle open, or "blip" a foot throttle, and these engines will take a second or two to catch-up.

  • HiYa Rusty-
    No, Ford 9N, 2N, and early 8Ns used the Marvel-Schebler TSX-33 carb, then switched to the newer M/S TSX-241 carb soon into 8N production. There is no such model number (TSX-251) listed in the M/S Manuals. I think you may be looking at the brass date code/ID tag that was riveted to the carbs. It would have the model number plus the manufacturing date stamped on the tag. "2 - 51" sounds to me like that is what you are looking at; denotes build date as February, 1951. Can you post some pictures? If you used a TISCO carb kit meant for the TSX-33/241 carbs, and the parts worked, then it is probably the correct carb. NAA used the TSX-428 carb, and later Hundred Series carbs used other models. Parts are slightly different and do not interchange with N-Series models and these all mounted on the LH side of engine; 9N, 2N, and 8N carbs mount on the RH side. TSX-241 Brass ID/Date Code Tag:

  • Rusty-
    I received the photo you sent and frankly can't explain the TSX-251 stamp. I see no model number reference at least not for any Ford Tractor carbs -see LINK below. If it looks like a 241, fits fine, and parts kit works, I suspect the stamp was an error at the M/S factory. One of those odd parts that may be worth hanging onto. Maybe someone else can show otherwise...

  • Iím going to guess that one of the small passages is clogged. Take it apart, soak in carb cleaner, run a wire thru all passages. You can research the 251. Probably from a different tractor but should work for you.
