Started having some issues with the ball return on my BK2K. After a ball drains to the bottom
of the playing field there is a switch that the ball falls onto then it pushed a plunger to the left.
At a certain point this plunger engages a coil that kicks the ball over to a staging area waiting
to be sent to the plunger. Recently for some reason it take the ball a while to push the plunger.
There is a spring attached to the plunger that looks like it is supposed to help move the plunger
but it supplies almost not help for the plunger. Eventually (after about 10-15 seconds) the ball
pushes the plunger far enough and activates the coil. It kicks the ball over and the game continues.
Any help would be appreciated.
