I have completed the conversion. Flushed and cleaned the compressor, all new o-rings on the entire system (that took a while), new dryer and orifice tube. All is well but I now have a squealing noise coming from the orifice tube. I used a variable design, which was recommended and am planning on doing an evac, replacing the orifice tube and then doing the recharge. It runs great, super cold air, but sounds like a dying animal at times!
