98 ZXI 1100 needle jet seat - missing?
 

Hello. The ski won't idle for poo. Runs great at 3000 rpm and higher.
I took off the CV carbs and when I looked at the seat for the jet needles, I think what I am seeing is that the center carb jet needle seat is screwed up/worn out or missing. See the photo at :

but when I go to look for that jet needle 'seat' part, it is not listed by any businesses (such as power's edge etc). Almost looks like I'd have to get the whole carb body. Ouch.

Am I wrong and it isn't the jet needle seat?
or if it is, how do I figure out how to get the part?

Is the jet needle seat threaded or pressed into the carb body?

Prior to this, the center carb's vacuum valve assembly had disintegrated, while under a previous owner. That was replaced.

Thanks to all
