Update: After returning everything to normal, I tried one final attempt to run the furnace. It actually started and I ran it for about 45 minutes. The longest it has ever run. I also learned that the regulator only makes a squealing sound when running off the drivers side bottle. No noise at all from the passenger side. I still believe there is some sort of issue, but it was good to get it running and have it stay running.
