Whilst testing various switches etc for my Funhouse, I've noticed a bit of a niggly issue. Where the ball lock is in the hidden hallway (1/2 moon type), if I push the ball around with a bit of speed, the ball won't lock and it just moves (ie turns with the correct movement of the mech). If the ball goes in slow, no probs and it works correctly.
It seems to be adjusted in the correct position - ie the ball is not bouncing past or anything else.
Do I need to put a stronger spring on the plunger to stop this happening?
