Now this is for R12. If you convert your system, make sure you do it right, Oring, flush etc, The amounts for R134a freon will change.

Had only 7-8 lbs of pressure in the low side. It did take the 12 oz can of r12, but it was VERY slow. It took 15 minutes or so for it to suck it in.
At the moment, I haven't been able to check the high side pressure. I certainly do not think it is high. 2 reasons: 1) My compressor continues to run, it would shut off with high pressure -- right? 2) My high side hose should be hot, or at least warm, due to the pressure (with the low side cold) but it is just barely more than ambient temp.
Any comment on why it took so long to suck down the can of r12?
Also, my sight glass was VERY cloudy -- looked like milky bubbles. It is only somewhat less bubbly now. Probably needs part or all of another can of r12. I'll wait on testing both pressures before I do that, though.
