If it happens when you move from F or Eb to G, it sounds like it probably happens when you move from a lower section note to G by raising the three ring key.

It might be difficult to find the issue without having the clarinet and you there and hearing and seeing it happening.

- Maybe you are raising/moving the left hand finger from the lowest tone hole (or any finger) when raising the right hand fingers from the ring keys. It's possible that you only do this when moving to G. For example what happens if you play F to Ab or F to A? Or Eb to Ab or A?

- It sometimes happens that the linkage of the thumb F to first finger F# touches and raises one or two of the trill keys. It can be just enough to depend on the amount of force you use. If this happens, then the problem is worst for C6 and B5, getting better the lower you move, however it's possible that only when you use all of your left hand fingers (e.g. for G) you press slightly harder to raise a trill key. Slim chance of this but worth mentioning.

- Many other possibilities of something in your fingers and/or your embouchure changing when releasing the grip from the right hand, with support only by the left hand. It might happen with G if it is only happening when you have the third tone hole covered (somehow making you move your fingers differently).

- If the three ring key is binding, it might not open enough when you release it. If it is opening just a little it could cause what you describe. It might be binding just enough so it only opens fully sometimes, and/or when releasing the D/A key (left hand) the added spring force does make it open (in the latter case moving to G, G#, A and Bb could have the problem, as opposed to only G). It could be binding in a way that something in the way you press and/or release the key is causing it.

- The same "binding" could happen from a problem in the bridge linkage. The two arms can sometimes have friction at one of the edges, as opposed to only top and bottom like they should have. It might also be just enough so it only happens sometimes, or only pressing the keys a certain way causes it.

Just a few possibilities.

You can try rotating the section slightly and see if it is better or worse (try both directions).
Try opening the middle joint a little and see if it better or worse (or the same).
Check if raising your right hand finger(s) fast or slowly affects this in any way.

You say it happens sometimes. If it is happening, does it keep happening until you play again another time (e.g. disassemble and reassemble the clarinet)? Or can it happen one moment and a second later it's fine?

If you have a webcam I can try to see if I can help you find the problem through Skype or something like that.
