Need help with my carburetor!!

[Upbasher]

Okay I have an air leak....figured out its that the carburetor was loose. So I go to tighten it (I push it in and tighten up the screw.) But after that the carburetor still swivels left and right?!?!?!
And when I loosen the screw and try to pull on the carburetor to take it off the engine, it won't budge even though it will swivel left and right.
This has me totally perplexed....help would be appreciated.
Thanks in advance

Ok when you loosen the screw tap it lightly but sharply to push it in. This will knock half of the pinch bolt loose allowing the carb to be removed from the engine. The metal collar on the base of the carb has probably come loose. I use ca glue to reattach them after I brake clean then to remove any nitro fuel residue. Then aplly a small amount of rtv sealant to the carb and reinstall allowing sufficiant drying tome before running.

I got it off. I took my older carb off my 4.1 and put that on and it fits perfect.
The 4.1 carb is the same as the f4.6, right? The only difference I can see is the color.

Yep the carbs are the same
