Your engine sags rearwards towards the firewall. Motor / transmission mounts?

I'd say you have more than a few small kinks to work out.

Indeed, you may want to clean the engine bay at a self-service car wash or a hose with nozzle and warm to hot water at home, watching electrical bits (connectors, distributor). Foaming engine bright and let soak, or simple green and let soak, with a nozzle spray and clean it up.

Do you have service records? Brake fluid bright, golden and clear, to no more than the dark tan in the brake fluid reservoir? Timing belt last changed when? Or at least tension reset.

How old is the engine coolant?

Check OBD codes for a lark?

As for whether R12 or not, well, turn the A/C on and the fan on with temp control set to cold and recirculate in. If you have charge enough, the compressor clutch will engage. As you are told, you can jumper the switch to engage the compressor to verify the compressor works.

Yet you have the condenser fan. These can seize. With cold engine off, spin the plastic blades.

You have refrigerant options if the system can hold a vacuum or has some manner of refrigerant in it.

Working with R-12 requires a U.S. federal certification.
