Need carb parts '71 CB350G

Hello folks.

Working on a restore of a 1971 CB350G.

While removing the jets, one of the jet holders/emulsion tubes decided it was time to self destruct and we'll need a replacement (or two would be nicer).

Trouble is, the part is not listed on the parts diagram; it's not the primary emulsion tube that the needle slides in, but the threaded tube next to it, under the mains.

Reference THIS THREAD for more clarity.

Anyone have a parts carb they can pull one out of?

The only source for one I have found is out of stock until October.

Thanks!

How badly are the emulsion tubes damaged? As long as you still have part of the top, it will still work.
Here's a pic of mine before I sent them off to PJ. He said it was alright to use it.

One of them is missing the entire top portion of the head, and the other is pretty rough.

Need one for sure, would rather have two if I can.

I was able to buy a set of parts carbs with good diaphragms even, for a whopping $50.

Thanks!
