1973 Johnson Rebuild. Crankshaft Bearing Oiler?

Hi. This thread is a continuation from my originally posted thread '1973 Johnson 135hp Ignition / Tachometer Issues'. Basically, an issue I had with my tachometer evolved into an engine rebuild - rings, and 1 piston.

Attached are pictures of the upper crankcase. I mistook the 'oil plug' (whose brass remnants can be seen on the side of the bearing saddle) for shrapnel and went to town removing it. Whoops. Big mistake.

My question: what is the purpose of the hole beside the bearing dowel? It has what appears to be a brass orifice within it. Is that a bearing oiler of some kind?I don't understand how it works.

The reason I ask this is that I'm not sure what to do next. Do I need to 'finish the job' with this 'oil plug' and drill it right out, I'm wondering if there was a passage there that connected to the 'oiler port' and I need to repair it to open it back up. Or, do nothing: the brass piece is called an 'oil plug'. This would suggest that the hole in which it was inserted was 'plugged'. I've never seen a setup like this before.

Edit: You might wonder why part 310507 is called a 'oil hose plug'. It appears to be a mistake on the item detail page. The parts diagram does call it an Oil Hole Plug.

If you look in the bottom of the cylinder you will see a small hole and this is that passage. It is drilled at a angle up to cylinder and then it is intercepted will drilled hole with oiler....
 
Yes, there it is. And it all makes sense now. So, knowing this, I'm going to smooth out that crater as best I can and continue on. Thanks again!!
