Having slight trouble getting the ball up the l/h ramp (the one that drops when multiball starts) with the right flipper. the back levellers are wound nearly all the way up so its not too steep. cleaned out the flipper plunger sleeve, it's not binding and slides in & out beautifully. The R/h flipper coil is a blue 11629 it's not a genuine Williams though. Anyone got any suggestions? The flipper feels strong enough. Never had this trouble on a previous Creech. Do coils get tired or would a slightly stronger coil help? Thanks if anyone has any tips or help etc
