I'm still very much a novice to chainsaws, learned a lot from you guys on here so far. I have a Husky 359 that I popped the top end off and I swear it has crank stuffers. Did Husqvarna ever make them like this? I thought only the 357xp had them. When I get a chance I'll try to get a picture. Is it possible someone added them? And if so, what would be the benefit?
