Recently acquired a Getaway High Speed II.
When you have all three balls locked (green, yellow and red) they will not release. The plunger opens to let them through but they remain static and do not roll. All the three switches appear to work, and the plunger drops but nothing moves.
If you put a single ball in and the plunger drops it release, but when you have three they seem to stick together and not want to roll.
Brand new balls, everything else seems to work fine. Disassembled all the switches, tried quite a few things but just cannot get it to drop the balls.
