I got a new game (tee'd off) yesterday and the VUK seemed like it was having issues intermittently. It just didn't have enough kick to lift the ball into the wire habitrail, but only once and a while, the rest of the time it works perfect.
I discovered it was only happening to one ball, so I removed the 4 games and weighed them.
In the 4 balls I weighed, I found that there was almost 2g difference from the lightest to the heaviest ball. No wonder the kicker was struggling for that one ball.
So, I was wondering, in multi ball games do you check to see if all the balls weight the same before you put them in the machine? So that all balls play the same
