So a little update on my experience with my 150.
Overall I like the saw. It's obviously light and has decent power especially for it's size, a huge plus when hanging by a rope. Always starts 3-4 pulls when cold but is a bit cold blooded, a glitch in the carberation that I haven't quite figured out yet. Richer settings only seem to cause other issues like loading up at idle and too much fuel ie loss of rpm on the high side. Warm starts are always one pull.
The positioning of the drive sprocket being back so far tends to cause it to fill the side cover with chips when cutting soft woods like pine, basswood, poplar, etc to the point it can completely bind things up and stop the chain. Diligent cleaning helps but doesn't eliminate the problem.
I really wanted to try the Lp setup but wonder if it would only compound the jamming issues with the larger chips.
One other thing I noticed that isn't really an issue but rather annoying just the same is the oiler seems to not be automatic. Meaning it's still pumping when the saw is running but the chain isn't moving. Make a cut, let idle for a few seconds, hit the throttle and it slings bar oil off the chain. When your up in a tree and this happens you inevitably get some on your safety glasses and without a good way to clean them up in the tree is a pita.
Definitely not getting rid of this saw. I would really like to get the carb figured out tho.
Any of guys have any input? It would be great to hear your experiences.
