Anyone have a Gen VI 502 block on the floor?

Cleaning up the Gen VI 502 block and either the 2nd from the front , lower steam hole on the Port side is blocked or blind??????? It is the small round hole just above the upper, rear, port motor mount hole.

Looks like it is blind. I hate to take a drill to it
THANKS!

It is just plugged up. None of them are blind. Pretty common for them to plug up. It should break free easily. Just tap a pick or something pointy through it. Should go right through.
