Best way to fix binding tenon?

Hi,
I recently bought an R13 off eBay and had it repadded.
When I received it I noted right away that the bell was difficult to remove and there was a new tenon cork on the lower joint that was finished unevenly (the cork was out of round slightly).
I brought it to the attention of the repairman and he said it could be binding tenon or bad cork.

He replaced the tenon corks but the bell still felt a little too stiff when I was removing it, and it was even more difficult to remove after I played the clarinet last night.

While examining the bell I noted uneven surface inside it where the tenon is fitting. There is also a small superficial crack (or posibly deep scratch) on the inside surface of the bell.

The tenon end, on the other hand, looks fine and has no obvious deformities or defects.

The repairman called me last night asking how it played and I told him abount the binding-he replied "No problem, play it a litle more and if it does not get better it means the wood is binding, not cork. I can shave the tenon a little bit".
After I spoke to him, later at night, I measured the edge of the tenon- 23.5mm.
The barrel deeper inside was only 23.3mm, which confirms wood binding.
I am not going to play it because I am afraid that I would not be able to remove the bell.

However, my question is: should he shave the tenon end or possibly inside the bell?

I am thinking inside the bell because there is not much thickness on the end of the tenon (my e12 has thicker edge there than this r13).
Thank a lot for your advice.
