Big saws,upwards of 100 cc and over I have several Husqvarna 2100 ,Mc 105,two 125's .Homelite 2100 S in the avatar and 1 084 Stihl I'm kind of raising as a foster child .
None of them has seen any real action for 4 or so years with the exception of a short run at a GTG .
Fact the largest displacement saws I've done any real work with are 81 cc,One 805 Mac ,an SP 81 and a 281 Husqvarna and those rarely .Most work being done is with either a souped 038 Mag or a souped 038 AV .
Seldom in these parts do you find much over 24" .The rare 30 and 36" stuff if it amounts to anything I cut into saw logs .It's not worth the time to drag out one of those larger saws to make just a few cuts with .
