Found two leaks, fixed with new o-rings. Charged 2.028 lbs. of R134a.

With outside ambient temp at 97 degrees the vent temp is between 46-47 degrees. This was on the test drive where I drove on the interstate. Stop and go traffic is not that low of vent temp. But it's always been that way since it's a converted system that used to hold 2.4 lbs of R12.
