Help on a reach in cooler 134a compressor issue don’t know what I’m doing wrong

I’m working on a blue air make table my original call I had a locked up compressor plus unit was flat had leak on the discharge in drain pan. Had a Samsung compressor Originally to get a compressor quicker I crossed over to a Tecumseh got the new compressor when changing it out had no pressure in compressor when pulling the plugs put in anyway weighed in the charge pressures equalized fire up compressor terrible noise not pumping high amps then locked up. Thought it was bad compressor from factory Got another replacement found a restricted bend on the liquid line to the cap tube fixed fired up compressor did the same thing terrible noise not pumping locks after few minutes of run time. What could I have done wrong to cause it to the same thing cap tube I blue three with nitrogen not plugged pulled a vacuum and held.

Any ideas what I did wrong feel like an absolute fool telling the customer it needs another compressor
