Dustin, I went back out to my shop, Kroil oiled it again and vised up the ratchet, and gave it another good smack and felt the pin move.
Yep, got it out, then vised up the yoke and squeezed the "goal posts" closer.
A few times squeezing, and re-installed the pin.
It's much, much tighter now, and no more flop.
I expect this will have to be done after the next use of the ratchet.
But, no problem now as I can always tighten it again if necessary.
So, this 1975 vintage ratchet gets it's place back as the # 1 ratchet to go to.
Thanks for the help. Chuck
