Supco RO41 no capacitor, I use that on everything with a 95% success. I have used that after a manufacturer relay would not start it and is still running 6 months later.

ok let me ask u a question on that product  [ro41]      the package says that if comp uses a cap   to install cap in series with white wire.is that correct or a misprint?their other unit 810  says to put cap in parallel with red/white wire         when i tried the ro41 as instructed it wouldnt start comp...?

Depends on if it is a run or start capacitor. I have installed on both without and had no problems. If it won't start with a RO41 it won't start with a genuine relay either I have found. Once the relay is gone they are on borrowed time I tell them. If the RO41 won't start it a 410 with the cap may but it won't last.

That's what I do, and if it goes leave it alone. 90% success rate that they keep going.

All the new compressors are smaller horse power. Using a rco410 will only burn out the windings. If you have to,  use a rco810 or urco810. It will buy them some time but won't burn out the windings.
