My TTR's right flipper seems like it's not as strong as it used to be. The pinball is having trouble making it up the ramp. What's the cause and solution for this and is it possible to replace it with one that's stronger? How are they rated as far as power vs strength or what not. Yep I said what not. Usually dont but it seemed to fit, anyways I guess I'm looking for a lesson on coils. I haven't found a good one on the net yet. I'm sure someone knows where to find it. Thanks.
