The left flipper on my machine started dragging across the playfield tonight, so I checked underneath. The previous owner had installed a larger wood screw to hold the bushing tight, but it had come loose. The others weren't in much better shape, and I couldn't get them tight. I tried toothpicks, but that didn't help.
I'm thinking I'll just rotate the bushing to solid wood and drill new holes. It will throw off the return spring tension between the two flippers slightly , but I can live with that.
Does this make sense, or does someone have a better solution?
Thanks for any input.
