Homelite Chainsaws

A 26 LCS question
I got a seal for the flywheel side that was leaking and installed it.
Then I pressure tested again and found a hole in the crankcase that leaked under pressure. It is on the edge close to the belt case.
Is this a case where it’s supposed to be open ? The parts saw I have has a casting mark but no hole
Thanks

Doing some thinking, but can you see the crank moving through that hole?
Because, I believe that should be the outer race of the main bearing visible.

Edit: I take that back. The bearing is the raised area to the left of that hole. Must be looking at the crank between the bearing and the seal.
