are you able to pull on the bat upwards and confirm that there is a little play to ensure the flipper shaft isn't binding on the flipper bush and there is free movement of the assembly?

are your transformer lugs joined according to your wall outlet voltage?

yes it affects the power if the EOS switch is closed but not making excellent contact as it's not isolating a coil winding.

with the flipper down and the EOS closed you are skipping a coil winding by creating a short, that being the EOS.

the EOS shorts the high resistance winding leaving the low resistance winding being your 'hit'.

as the flipper crank turns with the bat it opens the EOS breaking the short and bringing in the high resistance winding so as to hold the flipper up and not cause the coil to get hot.

what gap do you have when the flipper is up and contacts opened?

i get you changed both flipper coils, but did you check the resistances prior to fitment?

as long as you can 'flip' the spinner and it spins freely with multiple revolutions then it's fine.

having said that the tension on the contacts underneath need to be correct, you may have it that the thin blade is having to flex/bend too much causing resistance to the spinner rotating?

did you remove a wire from the EOS to test the resistance?

have you checked the downward tension of the long contact leaf blade that it's not pulling down to much causing resistance for the spinner to rotate?

what gap do you have when the EOS is fully opened by the flipper crank?

curious if it's opening too early?

also the second pair of switches....are they making contact close to the end of the stroke?

curious if either or both switches are putting too much tension on the crank?

also do you have the same compression springs on both assemblies?

anything from post 32?

also have you checked that the link arm isn't rubbing up against the playfield?

also doesn't look to be much 'play' either side of where the spinner arms go into the bracket? you could elongate say the right hand hole in the bracket to take the arch out of the bracket and add some room for the spinner to move left to right.

I'm only going by the pics, it may be fine?

Have you thought about using taller posts each side?
