Hello everyone. I have a 1997 williams no good gofer. The Left bottom flipper seems to stick/stay up sometimes. I opened the machine up and everything looks ok, I moved the return spring of the flipper to the other side of the bracket it mounts to which made the spring tighter and seems to have resolved the issue. Do these springs tend to go bad? I cant tell if there is a bigger problem and have a tighter spring is only hiding the issue.
