He needs to remove the brass seat not the needle. The brass seat is sealed to the aluminum carb body with an o-ring that has gone bad in his carb.

Ahh yes. That's what they look like. The 28s are direct into ally. That larger ones pressed in brass. Try the ball bearing and new tip needle but also have a real good look in there and back flush so any debris is ejected out the inlet. Hairs are particularly troublesome.

Hi F5, completely off topic this...
I see you have a RZ/RGV hybrid, would love to see some photos of it, can you send me some? I've owned a RD350LC, 2x 350YPVS, an RGV250 and an RG500. I just love 2 strokes! All the best, Dave.

You need to thread the brass seat with a tap, put a screw in it and pull.

Well looky, the latest Practical Sportsbike magazine has just such an article.
Its working on a Kawi ZRX which has Keihin CV carbs but principle is the same. Apparently an M7 tap fits nice, screw in a bolt and heatgun the area and yank. Ideally with a slide hammer but shouldn't need one. Only drama is M7 bolts are hard to come by. However my Marzochi triple clamps had them so borrow one. The got a replacement from NRP carb parts in UK. You'd have to measure it and request if equivalent available. They measured how far it was pushed in and copied that with the new part. Also thinking. . . was it leaking around the side? Shouldn't really with an interference fit. Wonder if you could seal that with a suitable wick in Loctite or similar that could cope with the petrol. Not thread lock, they do heaps of other stuff.

Isn't that what he was trying to do? I did give solution to try before that method.
Another on they mentioned that I haven't tried is a cotton bud in a battery drill with some metal polish.
