Having an issue with Fishtales where if the ball drains too fast the next ball hasn't made it into the hole in the trough yet so nothing there to kick it out, watching the coil after it kicks the ball out it very slowly goes back down, like it's staying up too long preventing the ball from taking its place in the kick out hole, if the ball is in play long enough it does drop back down eventually to allow the ball to proceed as normal. Could it be a replacement spring that's needed?
