Sorry, been too busy to get back here.
if you are getting cold on the small line, you need to have all the refrigerant removed, then open the system and find the blockage and remove it. if it is cold right as it comes out of the receiver, you will most likely have to remove the receiver.
it sounds like the P.O. just dumped in some pag oil and 134a refrigerant, and called it a day. not too good. if it is overcharged, your compressor could easily be destroyed, but it may be ok.
