Hello all. Just purchased a lid gasket for the mirro-matic 22 qt pressure canner since the old one would leak up until the pressure built up and I wasn't having that. Problem though, can't get the lid to even close with the new gasket on. Won't budge a bit. Any ideas or suggestions? In comparing the two, the old gasket besides the new one is like comparing a saltine cracker to a Big Mac, really large size discrepancy. Any tricks of the trade that I am missing or what is going on? Lid gasket is for the 12/22 qt canner, and says it fits this model.
