I am LOLing at the "10mm 044's have issues".I have 2 of them... both built in '92 or '93. Both have the large port stock exhaust and both cylinders are stock. They simply rip... Prolly my all time favorite saw to fall with. Been thinkin' about havin' one of the cylinders "cleaned up a bit", and see how it does...
Nowthen... the BB kits... they are just a bunch of junk if ya ask me... You couldn't pay me to use one.

The reality is, your experiences won't be the same as others'...what works for you won't necessarily work for say, the guy bumping knots on a landing or a hotshot crew sawyer doing heavy initial attack on a rolling large fire. Your saws see occasional use, they are not running hard 8-10 hours a day.
