I have finished restoring my Time Machine. I replaced the flipper bats and coils with the original ref from Pinball Center. I can manage quite well. However, the inner left flipper is not powerful enough to kick the ball across the ramp. I seems to be good enough for the ball to reach the top targets but the half circle ramp no. Voltage is good.
What can I do ? I was thinking of a more powerful coil, but which ref ?
