Is there a carb kit worth bringing home anymore? Needs the full kit. Steiner? Do I just go to AGCO?

AGCO I don't believe will have a "kit" anymore. The 175 carb is kind of an orphan model Marvel-Schebler. AGCO might be the only place to buy a throttle shaft if they even have it. The gasket set parts should be the same as a late D-17 IV. The needle and seat is 70226458 the same as a D-17. EDIT: AGCO shows 70226470 for a gasket kit and 70251721 for a repair kit. Whether they have them anymore, I have no idea.

If the Doc’s suggestion doesn’t pan out, I have been getting kits from Mikes Carburetor. If you have the carb number you will likely find it on their website.
I got a kit for my Allis FT20-25 and IHC grain truck which has the Holley governed four barrel

But, neither one have a throttle shaft in them. 70251709 is the throttle shaft.

If the throttle bore is worn, a new throttle shaft isn't gonna do ya any good. It's the bore that wears out, not so much the throttle shaft itself. Depending on how much play is in the throttle shaft, I'll either sleeve the bore or if there isn't a whole lotta' play sometimes an oversize seal will tighten things up. It just greatly depends on how worn things are. HTH Steve@B&B
