  • Carb advice
  • You all have been so helpful I'm back to get your opinion on what to do with the carb I found on my 9N. I took off the Marvel Schebler carb and the only ID marks are a G stamped on the side by the fuel inlet, a 21 by the larger adjustment screw, a 6 on the bottom of the inlet, and on the bottom of the fuel bowl is a 10A 555. It looks like the carb in the pictures of how to rebuild N carbs. One site shows G series carbs produced from 1909-1921, but there's no pictures. Steiner shows an early N carb that looks like mine with a G on the carb, but it also has the Marvel Schebler words on the bottom half of the carb and mine does not.

    The carb definitely needs a thorough cleaning as the needle wouldn't drop out and the brass floats were tarnished...although they cleaned up real good and passed the float test. I'm trying to decide whether to go buy a gallon of carb cleaner to soak it in, get a carb rebuild kit for an early N and go to work, or just buy a new carb for $89 off Amazon, or get a rebuilt or rebuildable TSX-33 carb so I know what I'm dealing with.

    Maybe I'm overthinking this. Just wondering your experience/thoughts/advice. The tractor is to be used on a small hay farm to tedder, pull a NH rake, and for shredding.

  • Mark-
    The original carburaetor used on the 9N, 2N, and early 8Ns is the Marvel-Schebler TSX-33 Model. On the 8N, Ford soon went to the M/S TSX-241 Model. Both of those carbs work fine; the 241 was an upgraded model that's all. Here are some pictures of the TSX-33 carb. M/S carbs have a ping-paddle cast boss, with the "TSX-33" cast recessed on the boss, and the TSX-241 carbs went to a brass tag riveted on the boss with the model number and a manufacturing date code stamped on it. I don't know what you have and don't want to speculate. If you want, email me pictures and we can discuss further. I have some original M/S TSX-33 and 241 carbs and also do rebuilds. I wouldn't buy anything just yet. New stuff is not that good. Always rebuild these original parts whenever possible...my email is open.

  • New replacement carbs are basically junk. Most of the original type MS carbs found on these tractors have been rebuilt so many times there is no way to know what they are by the markings on the case. Most of them can be cleaned-up and rebuilt to TSX-33 specifications. I started treating carb rebuilds like an engine rebuild. I don't know what is needed until the carb is in pieces. Check all parts removed for wear and correct size, then order just the individual parts and gaskets actually needed for each carb. I clean and rebuild 2 or 3 carbs at a time, so I consolidate orders to save shipping cost. I have MUCH better luck buying individual jets than relying on any rebuild kit having the correct parts. This also costs a lot less than buying kits full of wrong size parts and parts that don't need to be replaced.

  • As an aside, I found an original MS repair manual online a few months ago. I don't know if its in the library here, but will gladly send it to someone if its not so it can be shared.

  • Mike, this is the one we have now in our Manuals / Service/Troubleshooting section here. Is it the same as yours?

  • Just8ns.com of course, GRIN. They sell by part number most of the individual parts I will need for any N-tractor MS carb that has been disassembled. I also keep a couple small drawers of good experienced parts from carbs that were not rebuildable for one reason or another. I've rebuilt many carbs that were already full of new parts, they just weren't thoroughly cleaned by the previous rebuilder.

  • Thanks for the advice. I just got called away to work for 3 days, but I’ll clean her up good when I get home and send you some pictures Tim. You all have a great weekend!

  • Re: Carb advice-new drain
  • Tim, I found under a layer of paint that my carb is indeed a TSX-33. We got it cleaned up with the hardest part being the drain in the bottom. It was real dirty and nothing cut it even with some serious soaking and high air pressure...so we drilled it out and tapped with 1/4 NPT. $5 off Amazon for a Parker 047040004 Sintered Bronze Breather Vent, 1/4 " NPT Male, 0.63" Length, 150 psi. Got some work to do—Carb kit, tune-up kit, new 12V coil, sure seals, battery hold down hardware and pto bearing and seal coming from Just8N’s (Been GREAT to work with). Prices way better than NAPA and N knowledge off the charts compared to what I get at NAPA. Thanks for all the pictures//they’ve been really helpful. I need to figure out how to post pictures...just hate opening up another account.
