I have a International 404 that I think has the Marvel Schebler carb on it. I would like to rebuild it but I am leary of doing it. I think it is a 824. I can get a kit for it at the tractor supply close to me. How hard are these to rebuild? I tried to rebuild my 66 ford 352 2 bbl carb twice and finally gave up and bought a rebuilt one. The one on the tractor looks to have less parts. One thing I am leary of is the rods that move. The round dowels that go through it. I wonder if the carb has too much wear around where they go in. I am somewhat mechanical and I rebuild power tools as a hobby. I have rebuilt a lawnmower. So can these be rebuilt by a tractor novice like myself. The best for me would be to get a rebuilt one but I don't want to pay over 250 bucks for a rebuilt one. I could get someone to rebuild it but it would be pricey. I would prefer to do it myself.
