Bought a new carburetor

[bw1982]

Got a new kipa carburetor from amazon and the main jet is bigger than the original. Is the main jet the only difference between the small throat carburetor and the bigger one

The bleed and discharge tube will also be different.

While we're on the subject
I just brought home a '47 that l bought at auction on line. So virtually sight unseen except for the pictures they posted. It has a few problems l didn't anticipate. One is the carburetor. It could be a Zenith but l'm not sure, as l'm unfamiliar with them.
Personally l want to take it back to an IH carb. I've read other threads where people were having problems with the current after market carbs.
My question is this. Which is the best after market carb and supplier, or do l search for a rebuilt or rebuildable original?

Sorry to the team, l don't mean to hijack someone elses thread. Just looking for info.

Misprint my new one is a '48 not a '47.

This is what the Zenith carb looks like...

There are two aftermarket carbs currently on the market to replace the original IH carburetor. One is available from TM Tractor Parts, and maybe others. It sells in the $200 - $250 range. The other is a significantly less expensive one available on eBay in the $40 - $60 range. These go by many names, but they are all the same carburetor. As you might expect, the more expensive one is the better of the two. If it was me, I would find a good used IH carb and rebuild what was needed.

Here's TM's carb... http://www.tmtractor.com/new/fl/125fp.htm

Thanks Don, that's the direction l'm leaning. According to sponsor JP Salvage, all of their carbs are rebuilt and ready for shipment. Still doing research, but probably the way l'll go.

Most carbs bought will need to be tuned or adjusted in some way. That either means an external adjustment for the jets, Idle air adjustment, or a float drop setting. (regardless of whether it is new or old or rebuilt)

Why not rebuild the Zenith? There are thousands of Zenith carbs running C-60 Engines. (Tractors, Boats, Bailers, etc) They are not a finicky carb and there aren't many moving parts to them.

Outdoors,
I'm just more familiar with the IH carb. Easier for me to stick with what l know than deal with the unknown at this point in my life.
