Dumb things that you did.......because you didn't know any better.

Thanks to everyone for sharing their stories. It takes a good spirited person to admit their mistakes!
I've made plenty...BUT I feel that the guy that makes NO mistakes is the guy that never tries anything. You can't screw up stuff if you never leave the couch.
I look at things and wonder how they work. I ponder odd ways to fix things too, sometimes. Add to that the occasional tendency to just jump in without knowing what I am doing and mistakes are sure to happen.
With my first car, I decided to change the points. 1969 Dart with a 318.
I pulled the old ones out and put the new ones in. It wouldn't start. Guess why?
Yeah...I didn't set the gap. How the heck should I know that it was necessary ? :eek:
I've driven cars after forgetting to tighten the lug nuts.
I cleaned the sludge in the top end of a Honda Civic, only for the sludge that fell through the drain holes to block the oil pickup and caused a rod knock.
I once set the air gap too wide in my '70 Charger and tried to drag race it, only for it to pop and sputter to an embarrassing ET.
