How tight should they be?

I am replacing the idler pulleys. On the pulley on the right, if sitting in the seat, how tight should the bolt that goes through the deck that holds the arm on be tightened? How about the bolt holding the pulley to that arm? Should they be TIGHT! or a little loose to allow the arm to move?

Post the units model and serial numbers so we have some idea of which unit you are dealing with. We hate guessing and our psychic powers are down due to COVID. We need to figure out it you have a shoulder both or plain bolt.
