Would this concern you?

I got a little carried away doing my u- joints before

how much of a dumbass am i for running it like this?

 

[bilzy7]

i wouldnt worry, its just a chip!!

I've welded up worse yokes and re-ground the snap ring groove into them. I would fix it rather then run it as is, it is a weak point now and you'll always be thinking about when it's gonna fail.

Run it til it blows! And make sure to always carry duct tape with you.

Or, do what wahlstrom said.
