Yes, we vacuumed it for approx 30 min befor charging. We added about 3 ounces of PAG oil.
Have you had a chance to put on the new compressor? Keep us updated.

i work on refrigeration units all day, i would like to know what your head pressure is, high side or red on your gauges. the charge you weighed in from what the sticker said was the weight for r-12 or for 134a, i know you put 134a in the system from what i read, but the system will use less freon with 134a than an r-12, your probably over charged, also you condensor coils are probably dirty and plugged with bugs, clean it out really good and see if that doesnt help your problem.
The compressor remanufacturer sent us a new compressor and drier. After swapping them out again and vacuuming/recharging the system we have good results. The first reman compressor seemed to have two problems, one with the rpm sensor and the other with developing proper system pressures. It's blowin' snowballs now! BTW the remanufacturer we used was KLK parts in California. I found them on Ebay...great folks to deal with and they stood behind their product. Thanks to everyone for your replies and help!!
