Repairing worn coil mount.

The part of my coil that the bolt goes through to attach it to the shaft was getting some grooves worn in it. I used some Weld Stick epoxy putty [ 4 few bucks at farm and fleet] to fill the grooves. I let it cure for two hours and used a small rotary file in my dremel tool to smooth it up. It looks almost as good as new and the coil is no longer loose. Good hunting to all, Merf
