Yep, I now finally know what's corrupting the threads... attaching pictures. Going to do some research on it tonight and see if I can't find a permanent fix.
Here's the picture that was missing and caused it to break. I moved the engine from the moving dolly to a stand with larger casters, battery & fuel tank tray. Will be hooking up the extra gauges I have for Tach, Volt, Oil Press and key switch.
