Sorry guys but can't seem to follow. Are we talking the only spring I can see that attaches near the yellow capicitor and goes to the pivoting section that actually hits the stop and activates the EOS. Reason being I can't see how this can be put on incorrectly.
It might have been removed...
Is a washer the size of a 20 cent piece will be either mounted inbetween the flipper coil and coil stop or the flipper coil and the other bracket.
