Look where you've wired the EOS switch to on the right side coil and compare to the left side
The dark blue wire is on the wrong coil lug - move it from the coil lug with the orange wire to the coil lug with the brown wire.

The simple answer is nobody makes complete early 80's linear flipper mechanisms you can buy off the shelf.
Most people prefer the earlier design for the reasons slochar mentioned and thanks to PinballLife, that mech is available.
