Like I said before I ran Kevins souped 166 at Chardon and had the stocker for a week or so to practice with .It was one powerfull machine but it wasn't as good as an 084 as far as user friendly .
I kind of put them in the same class as my 125 McCullochs ,Damned fine old saws but getting to the point it's nearly impossible to find repair parts for them .Those things were made to run giant long bars in old growth PNW stuiff which they can still do .Just how many 6-8-10 foot diameter trees does the average guy run into ?
