Carb swap

Doug-Iowa · Jul 14, 2016

I'm trying to get a IXB3 Hercules running, the Marvel carb that came with it is a basket case and parts are missing. But it "looks" the same as a Marvel for a 8N ford, which should bolt up. Can anyone school me on Marvel Schebler carbs and what they will swap with? For what its worth the carb kit website has a TSX rebuild kit shown correct for both the 8N and the IXB3. Tractor is a '41 Wards Twin Row. Thanks.

/S carbs were available with several throat sizes and in the older Ford tractors, 3 or 4 different mounting bolt spacings, not to mention JD & others. The 9N/2N/8N Fords had TSX33, TSX241, TSX241A, TSX-241B, all interchangeable, but some have somewhat better performance than others.

I took parts form a carb for a Oliver 60 and parts of a carb for an 8N ford and made a good carb for that Oliver 60 engine. M/S carbs come in 4 sizes small like on the 8N and medium and large and extra large. The carb kit I buy at O'Reilly's auto parts stores Walker brand is part #778-505A and that works on both the small and medium carbs

If it measures the same on the bolt pattern, the bore is close to the same, and the aluminum venturi (choke) is the same, the air filter connection is the same, it should function the same.

The most important though is the throttle linkage where the governor link connects. Be sure the direction of rotation is the same, the length of the arm, hole size, everything about it needs to be the same for it to regulate the RPM properly.

Those are simple carbs, don't be afraid to open it up and look around. Possibly you can combine the two into one.

Pretty much any MS carb will work as long as the bolt pattern to the manifold hookup matches. The issues are with the side (L or R) of the carb that the choke is on along with the direction for open/close operation. Same thing applies to the throttle linkage from the governor. Most of those MS carb linkages can be flipped from one side to the other with a little fiddling and ingenuity. The travel direction for the choke is a relatively easy change if it nees to be changed, the throttle linkage can be more tricky but can be figured out. I've changed several of them and once you know what you need, you can usually fabricate something that will work for both the choke and the throttle linkage.

Oliver OC-3 crawlers use the same engine.
