I have seen a couple guys use these mini chainsaws when laying out Enduro trail (Enduro = off road motorcycle competition in the woods) fits in a pack easy, cuts all the face slappers and small saplings pretty good. A good tool to add to the pack for trail layout, saves on all that muscle powered sawing.
You always got to adjust the chain after it heats up it will stretch and I've seen even a brand new song you might have to adjust the carburetor mixture not necessarily the idle speed
I just got the same blackmax blower for $64.50 with tax on clearance. I was using an old 25cc toro vac before then and and the Blackmax is a bit more powerful. Still wanna get a new carb for the toro so I can have a backup.
