I have rebuilt the flippers on mine. But I didn't replace the coils. The hold side of the coils seem weak. When the flippers are in the up position and the ball comes down and hits the flippers they will give a little until the high power side kicks in and then kick the ball back up. Does anyone else have this issue? Is there a coil with a stronger hold side that can be put in? The high power is plenty strong enough. It's just the hold side that is the issue.
Edit: I can't find a higher power coil to put in it. But last night I adjusted the EOS switch on both flippers. I usually have the switch adjusted so it has a 1/8 inch gap when it opens. I closed the gap so that it is about 1/32 inch. It still has a bounce back when the ball hits the flippers when they are up but it isn't nearly as bad as it was. I would still like to get a coil with a stronger hold side but at least it's playable now.
