Much cheaper to rebuild it or have someone do that. If it's leaking where the halves join together, the top is likely warped and the gasket is bad. When you separate the two halves, pull them straight apart or you'll break off the idle tube. If there is debris in the needle valve seat, that could also cause leaking.

Hi,
Here is a post where I wrote 3 posts about the IH carburetor, it has info about rebuilding it.
They can drip on the ground when sitting from dirt in the needle and seat, like Bob wrote above, or the needle and seat wears out after years of use, and needs replacing, or the float level can be too high, or more than one of those. :)

It's on the flat surface of the top above the float bowl. They are often obliterated if someone bangs on the top to try and loosen a stuck float. It will be a part #.

Hi,
The Cub IH carburetors had a part number stamped on the top, on the edge of the bowl. It is easy to see it, if it is there.
I think I have read on here that replacement carbs have no number there.
If you are buying a rebuild kit, I don't know if the place you are buying it would ask for the number. :)

Thinks, looks like there are 2 or 3 rebuild kits for it. According to the old owner it has never been rebuilt. It has the IH on the side of the bowl.

Before you buy a full kit, I'd suggest opening it up and taking a look. You may only need to flatten the top and replace the body gasket. As I said before, be careful you don't break off the idle tube.

If you can bring your carb to Cub-o-lina Cubfest you can probably get it fixed up and have an enjoyable weekend. Sanford, NC. June 16, 17th. viewtopic.php?f=8&t=92315

If there were not modification to the engine on the '47 the carb should be a IH 251234R94

Last year I put an IH 364579R91 on my mostly original 1949 and it was not happy running very rich. The same 364579R91 on a later cub ran fine and a 251234R94 on the '49 ran fine. Both carbs were freshly rebuilt by Mike Finch in MI and had main jets and idle tubes correct for the part numbers.

That is just my experience and I do not know if your setup is the same.
