Come on, why ya gotta be splitting hairs? 😁
OP said there was no flywheel with FD, I said that there was (with brief details), then you agreed by adding further details...sounds like we're on the same side on this one again...bottom line, tinkering with that FD coupling should be done with care as they can be easy to mess up with improper maintenance and scarce repair parts. OP has a long row to hoe before getting this beast rolling under its own power safely, and helping out with theee details is beneficial in reducing repair costs AND improving enjoyment factor 🏆
