When I acquired my Williams the Getaway off e-bay two years ago I found sum interesting things when I went under the playfield. For sum reason the previous owner lubricated the flipper coil plungers,,, a big No No.
I pulled down all three flippers with new linkages, plungers, plunger stops, plunger sleeves, retune springs and switches. I found the old flipper parts where caked in grease, its amazing how flippers still worked.
Here is sum before and after picks.
