Yeah, I know! The one which I put on the left in the first place operated way better. I rebuilt it now I put on the right and it's an improvement! Much less force needed to move the rear derailleur.
Gonna rebuild the other one and put it back.
They are quite straightforward to overhaul, by the way. Good to know for future tinkering.
