3000 Carburetor

I have a 1966 Ford 3000. In a previous post (see TWANK message below), I was having problems with a 'twanking' in the engine followed by rough running and generally bad sounds.

Initially, I thought I had a bad connecting rod, then using metal tubing, I was able to listen and locate the sound to the head.

I finally got the tractor broken in two as I needed to get to the head. When I got the head off, I found the main fuel jet had become dislodged from the carburetor and ingested into the intake manifold. This is a brass nozzel.

Is this a 'replacable' part, or do I really need to get a 'new' carburetor?

If it is replacable, what is the best method?

If it is not replacable, would it be better to get a Zenith or an original 'rebuilt' carb?

Any input welcome and needed.

It turns out that having it separated is a blessing.

Initially, I could not get the head off, because the air cleaner housing was in the way. I found out after I separated the tractor that I could have removed the four bolts holding the air cleaner housing and it would have been removed. (I have a learners permit.) Now that I have it in two, I found the clutch plate had separated from the center bearing, so I need to replace the clutch as well.
