I have a 727 that has been on the shelf for a few years. All worked when put up . Tried to slide the converter off the other day and it won’t. Spins , ricks side to side a bit but won’t come off . Fashioned a pul to tug it against and away from the bell but didn’t pop like I thought it might . Didnt go gorilla on it . Any thoughts or experience with this issue.
Thanks
