Gottlieb EM, weak flipper

[ringram]

I have a Gottlieb Duotron, early 70's vintage. The right flipper seams weak compared to the left. If may have the same stength in the relay, but when hitting the ball, especially at the top of it's travel, it seams to "bounce". I noticed this also when a ball comes down and hits the flipper when it the flipper is up.

Would this be a problem in the setting of the EOS switch? I was thinking of ordering a flipper rebuild kit.

Also eyeball contacts on EOS switch to see if the pad is still intact.  I've seen a few where the cause of that is a contact pad that is mostly gone and it's doing more arcing than connecting.
