Do it a few more times and you will get good at it - lol. Even that spring is not much of a bother after the 4th or 5th re-assembly. It was that tube holder that broke and started all my problems originally. Now I know what to do. I second you on needing a few springs. If you can’t find it, your SOL. So far, I have not seen it as a part that can be ordered.
The spring itself is not a problem. It’s just that the extruder + nozzle is bad. It shouldn’t clog so often. I had creality cr10, I have bambulab x1 carbon and everything works there, if there is clog it’s extremely rare and usually with wood filament.
