Hi, Im new to owning a pinball machine (about 2 months now). today while playing the mystery wheel did not spin when the ball when into dragula's cave. I put the ball into it three times and no spin. it gave me points (different value each time). any suggestions (he has been working fine since I bought it) on what to check. Ive never messed with a pinball machine so have no clue where to start. (in the Seattle area)..
