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.

using the out hole kicker picture B-8039-2 diagram: #2 Coil Plunger Assy. is the part
I was talking about. There is a switch under that #2 arm. The ball falls onto that switch
when the ball drains off the playing field (down the middle / down the sides) the ball then
proceeds to push on the hooked part of the #2 to the left assy very slowly. And after 10-15
seconds it will kick the ball to the right as it should but it never used too take that long. It
would immediately return the ball. I cleaned the coil and sleave and rod with alcohol but
no change. Also, the spring does not even provide any help moving arm #2.

will have to wait till I get home later this evening.

I figured it out. I tried to turn the mechanism at points 4/9 on the out hole kicker. it felt rough.
I hit it with a dab of Remington oil and it slapped back into place with no problems and plays like it should.

Thanks for your help.
