https://www.flippers.com/coil-resistance.html shows 4.7 ohms for the flipper coil, so your measured 7 ohms isn't outrageous. How does it compare to the left side? It's doubtful the coil is bad, more likely you shorted something during the cleaning process.
Test your working flipper. Do you get 7 ohms at rest and 161 ohms raised? If so, your right flipper isn't utilizing the EOS for some reason.
