Here's one from left of field the BSD I picked up recently had poorly performing flipper so I put a kit thru them both including bushes.
All good now and unfortunatly too good!
Ball will rim ride the left ramp and falls off the wire when diverted.
This is even with the genuine shorter flipper bats.
Would effectively smash the game to pieces if played in this state..
A quick check of the manual revealed the problem,

Coils are 11629s the strongest parallel coil I think,

Should be 15411s  orange label...
