If you look at the ears on your coil when you snug the wing nut down you will see the ears bending in.
Here is what I just did to mine and it seems to keep the ears from bending in when tightening.
I took the shaft out of the coil and removed one of the rubber gasket that plugs into the the side. I then took a plastic cap off of a gallon water bottle ( the kink that you have to pull the tab that tears around the cap to remove it), I punched a hole in the center for the bolt to go through then I used a Exacto knife to trim it to the diameter to fit into the inside of the rubber plug gasket/washer. I reinstalled the gasket plug and it spaces the plug out enough that when you tighten (snug) the coil ears do not bend in.
You may have to use a little rubber cement to hold the plug in because the tabs on the washer do not go in as far because of the spacer, just a "little".
I tries using a rubber washer that I purchased from Lowe's and it was just to thick .056) So I tried the inside of a one gallon water jug (.02 that seems about right.
