For Williams solid state games with either too weak or too strong flippers,
check the flipper coils against the list below. Williams designed various
strengths of coils, and if the wrong one is substituted then you will end
up with a mismatched coil. These are listed from weakest to strongest.
FL-11753 YELLOW: used with short flippers and close shots.
FL-11722 GREEN: used for close shots shots near drop targets.
FL-11630 RED: The Standard and most frequently used.
FL-15411 ORANGE: used on long playfield shots.
FL-11629 BLUE: used on long shots and high ramps.
Pay most attention to the part number. The wrapper color may be different
if your coils come from a third party supplier.
