I've got my World Fair working pretty good now thanks to this forum pointing me toward a good tech in the area. One thing I have noticed is that sometimes when the center wheel is turning, some scoring may be missed. In other words if I hit a bumper that turns the wheel, and then hit another bumper while that wheel is still turning, points can be missed and not register. Once the wheel stops turning, the scoring will pick up again the way it should. Any ideas on this one?

Yes they do. They say "40 points spin when lit". I wasn't sure if it did this before. Thanks DirtFlipper.
