Dear 50C;
I would just start over.
The parts/components that worked before are probably not the issue. So; double check all the new/different ones.
A parts clerk may have given you the wrong parts.
Inspect the springs in the hup (center of disc). They go toward the transmission. If you installed it backward they would have hit the flyweel bolts & be marked in some way.
The rest you know.
Good luck, John M....
