Putting the keepers on my very last valve last night and one of them "took flight". One second it was there and the next, it was not, didn't even make a sound when it landed. Just spent some time tonight scouring the garage, and nothing. This my first attempt at doing my own head work, and it's gone fine, and I was even aware this could happen, it's just kind of discouraging. Thought I would post this so we could all have a laugh, but now I'm actually wondering if some kind soul here on Mud might drop one in an envelope and send it to me?
