I did a search on this and, if the information I found is accurate, IH used the same 1bbl from 1956 until well into the 60's.

It is possible that you have a Holly 64-3135 or 64-3136. They are the same carb with the only difference being the 35 has a 2 3/4" flange bolt pattern and the 36 a 3" flange bolt pattern.

Those are the Holly part numbers. The carb may be stamped with the application number of "Holly 1904" or "H1904" or just "1904" somewhere on the body. I would look under the fuel bowl or near the flange.

Of course I have no way of confirming that this information is accurate but I think it is. I've owned a couple of Cornbinders myself and learned how to drive in a 1948 K5. I was a gear jamming, double clutching mother trucker back in my youth. My dad has a 53 IH that I may inherit soon. He and I did a frame up restoration of it back in 1968, Including a 12v conversion of everything but the starter and radio. No trouble spinning that engine in the winter. Throw 12v into a 6v starter and it flat spins. Figured it would burn out in a few months back in 68' but it is still spinning today.

Hi Ozarker,
I finally found some numbers at the fuel inlet. The are impressed rather lightly, but I think they are "172954 R9 1", then underneath it says "LIST 1418 1" with spaces before the ones. Another twist on this truck, I took it down the road today and as long as I left just a little bit of choke on, it ran fine, but as soon as I fully opened the choke at idle, it died. I haven't had time to check it out, but I think there is enough play in the linkage that the idle screw fell off of the choke cam, and closed the throttle completely. Ah the fun of antique engines.
Thanks,
Joe

Yep........that is a Holly. You can go to any parts store such as NAPA and order a kit for it.

Pulling the choke a little just allows it to run a little rich so if that makes it run better going down the road, the jet is probably dirty and not allowing enough fuel through. The idle circuit is probably also gummed up. Nothing that a good soaking in carburetor cleaner won't fix.

Assuming that nothing is broken or missing, a rebuild will probably make it just like new.
