Throttle controll question

[Rusty Homestead Fl]

Evening all. Cleaning up a throttle controll ( bolts to the top of the bell housing) before installation and have a question. Do the two oil holes on the top of the linkage that lubricate the cross shaft have some sort of "wick" type plugs in them or are they just left open. I would think they'd have something in the holes to retain the oil and help keep dirt out. If they do, what is used?
Thanks in advance, Rusty

Nothing in mine or others I've seen.

Nothing just a squirt of oil!!
