Few years ago, I bought a few 460's & 660's off a tree guy, he swore up & down that 460 meant that they were 46 cc.
Something to the affect of.... I've been doing this for 35 years, I know my saws.
I grabbed one of the 460's out of my truck (I had just paid him for) pointed to the sticker on the rear handle, where it says "displacement 77 cc" told him that's a game changer huh?
He insisted it was a typo or misprint....he proceeded to tell me he knew without a doubt, 460 were 46 cc and 660 were 66 cc.
I told him yeah, them germans really know how to build a saw, cause husky can't build a 66 cc saw, that will pull a 36' bar....
He said yes, your right about that, that is why I only buy stihls....
