Hope I'm not too annoying here starting a new topic as I didn't want to go un noticed adding this to an older post. When I'm playing my Williams Skylab something sporadically keeps sticking. There are the targets along the left and right side that have the long rubber bands and the switches behind them. When they are hit, 50 points are racked up. Sometimes when to hit one of the targets the scoring reels just keep going scoring hundreds of points before stopping. I checked the switches and all are adjusted properly. Is there anything else that I can adjust, clean or repair that will stop this from happening. You can play an entire game sometimes with 5 balls and it won't do it. Other times it will do it soon after starting to play. Any help with this would be greatly appreciated but if you could please tell me the location of what device I might be working with it would be so helpful. Many thanks in advance.
