My Dad has both a Stihl and an Echo Chainsaw...
The Stihl is a limbing saw, with about an 18" bar. The Echo OTH is a felling saw. LOOOOOOONG bar probably about 3 feet in length. Both start on the first pull and are well over 20 years old with Umpteen hours in them.
My FIL has a Husqvarna limbing saw that's only a few years old.
I would run any one of these any day.
1996 XJ, Bone stock. The build goal? Overland Adventure Vehicle. Nothing to radical, but nice and functional.
