Other than file cleaning the flipper button switches and end of stroke switches, the fiber flipper link needs to be checked or changed. To check hold the flipper coil plunger with one hand and the flipper bat with the other hand, and wiggle the flipper bat. the more play there is the less strength the flipper will have. Punching out the roll pins will allow you to change the link. Pinball resource should still sell these.

Wink The End, Of Stroke Woes...?

It is important for the End Of Stroke Switch not open to soon. Those contacts carry the bulk of the current flowing thru the main flipper coil. It they open too soon the coil will act real weak. After cleaning they should be adjusted to open only as far as necessary. As soon as they open the power must flow thru the holding coil winding too, as in>>>real weak flipper. Those contacts are supposed to self clean(sort of anyway) as they wipe past each other while operating. Like other pinball contacts they can benefit from being used. I have had flipper action improve during use shortly after cleaning those EOS contacts.
P.S. You can find troubles with EOS contacts by by-passing them with a clip lead. If your flipper acts right with the contacts shorted..."There's Your Problem Right There"
