The little Old Engine That Could

[Onex107]

You can't have anything in the valve guide while reaming. Dental floss? Wire? Not. If you could tie it to the end of the reamer and push it ahead as you reamed, then pull it back through, that would work. Special reamer for the rope trick? How about a magnet? Very tricky problem.

Sorry, I wasn't thinking. Wire or floss would lie in between the reamer flutes and help guide the stem back into the guide. I didn't know there was enough clearance for something tied around the end of the stem.
