Foxtrapper do you know what pressure you ended up with? I stuck with the recommended 80% of the 2 lbs of r-12, and my gauges read in the green for the correct amount of pressure, but it never gets that cold, definately not even close to the old r-12.

More than tread lightly. Leave it like you were never there, nor anyone else.
