My new-to-me Eight Ball Deluxe has a problem I'm trying to sort out.
When pressing the left flipper button, the upper flipper stays in the extended position. As soon as I apply a slight push to the flipper itself, it springs back to its resting position. If I just tap the button very slightly the flipper doesn't stick, but any normal use of the button will cause the sticking.
Is this a common problem, and is it OK to spray some PB Blaster lubricant into the shaft where the shaft goes into the coil, or is that a no-no?
I did swap one of the other flippers into its position and the same thing happens.
