I put a stew together to can this morning, put it into my 21 qt Presto
canner, and cant get the lid to close. It is on correctly, it just wont
turn to the closed position. There is a little pin sticking up to keep you
from turning it too far, but that shouldn't be a problem.

Does anyone have an idea what is wrong? I may have to wait until tomorrow
and call Presto unless one of you have an answer.

Thanks in advance. Dwayne
