Back in the day, ppl would climb all over these buggies while they were a-raisin he11...these flimsy hoods getting tweaked does not surprise me. Until ya get that flathead purring, you could probably roll up a hand towel and place it between the rad and hood...that'll get any squeaking to simmer down a tad.

Whenever I have run into screws that walk out, I apply one overlapping layer of Teflon tape to the threads...this has effectively wedged the screw in its mating threads without using thread-lock. On small screws, this is easier said than done, but sharp tweezers, steady hands and a good eye can get it done.

Maybe there is a problem with the fuel lines, possibly a pinched metal line or a collapsing rubber line...a reduced cross section on a draw tube will affect the pump's lift capacity, which can reduce its delivery rate to the point where it falls below the carburetor's operation threshold.

B-3 FD has the viscous coupling and a dry clutch and pressure plate.

It would probably be easier to drill out that retaining screw than get those hinge pins out, them two can be a real bear. They might have long drill bits at the hardware store that can make this task easier.

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 🏆

There's a flywheel in there with a ring gear for starter engagement, the fluid drive coupler is bolted to the flywheel, and the clutch + pressure plate are bolted to the coupler. additional information - miscellaneous repair details

Crawl under that beast and remove the flywheel cover, put a prybar on the ring gear and see what colorful german phrases you can utter...this might obviate the need to proceed on any immediate parts purchases.
