I wondered about the connection to the cam as well, I looked up while hand cranking the engine & I see the pump gear meshing & turning with the cam.
Only thing I can think of is cranking motor over with starter only the RPM's aren't fast enough to pull up oil into the pump let alone build oil pressure, engine has to run to make pressure. I cant imagine starter RPM's are at 800ish, probably more like 200 or less which seems like it wouldn't pull oil up at that rate.
Just speculation, I dont know. Thought maybe one of the hotshot engine builders of down under would know - I'll ask Rob at Action Machine if thats a reasonable guess.
It really seemed like the silicone plug I pulled out of the pickup tube end was the obvious stoppage, it was woven into screen basically capping the pickup - 4th pic, 1st post - looks like hair ball but rubbery
