I have an agata capper and really like it except for one issue. Every time I cap a bottle the bell ( I think thats the name of the thing that actually goes over and crimps the cap down) sticks in the down position. then it POPS back up. it is annoying. I have to manually push it back up or wait for it to slowly POP back up. I took it apart and can't see anything it is hanging on and wonder if it is SUPPOSED to stick down?
