Questions?? XZ-B question?

Weird to describe and wondering if someone could help out?

I took the carb off and looked down the block throat and noticed a small notch about 1/2 of a mm wide and it looks like a half moon right where the crank spins in the cast block in the front right side of the block.

It's so small I was wondering if it was a casting problem or does anyone else have this half moon or 1/2 of a mm circle in the side of the block by the crank?

The engine does not run any differently or was there any sign of internal wear on anything.... I took it apart to clean the carbon up on the piston (which looks like a brand new piston now with 1-1/2 gallons) is the only reason I found this 1/2 moon thing...

Thanks in advance!

I went to a LHS and found out they all have that after taking out the carb on a brand new one. Thanks anyway..
