Was leaking at the intake / cylinder joint this time. It is treated beyond poorly. Ham fisted, chains with tons of hook and really low rakers, 84 dl skip chains.. its a pure mess. It was leaking, yes.. it could have been tuned out though. Sadly they really start to sing and they get excited; "Man its really running good!!" --> She's coming apart!!
I'll try to get a picture of the chain that was on it.
This is the side of saws that a lot of hobby guys miss. Commercial saws catch pure grief every day.
