Chain bars and oil holes

[Sagetown]

My dad had to open up the hole on one of his bars. I think it was for his Jonsered 2055. I've found that a loose chain tends to clog up more easily. The chips don't get wiped out by the drive links as well. The Stihl oilers are a bit stingy, but I haven't had to mod the bar on my 290, just keep it cleaned out once in awhile.

That is strange, that only some of the STIHL saws have that problem. Very borderline I'd say.
