Just had to rebuild my left side flipper assembly on my Flight 2000. One of the screws that held the flipper bushing in place had come loose, as the associated hole in the flipper base had become stripped. So, I rebuilt the thing from the base up. The only things re-used were the flipper and the coil. New base, linkage, coil stop, coil sleeve, bushing, EOS switch and spring.
Since the rebuild, I have a little issue. When the left flipper is used, it tends to NOT return all they way back to the proper point. It stops just above that point, usually by an eighth or quarter of an inch. This is tough because it is basically impossible to use the flipper to dead bounce balls returning down to the left flipper. The play in the flipper allows for it to absorb the energy and the ball tends to just drain.
If you hit the right flipper button just once or twice after the left side comes back to rest too high, the vibration tends to return the left flipper to the right spot, so I don't see this as a big problem but I just want the flipper to work correctly.
