Yeah what I’m doing with this saw is beyond my knowledge and experience but it’s not rocket science either. I also started with a couple non running stihl saws on purpose to learn but at the same time not to burn a hole in my wallet. I cleaned carb and changed filters, lines and tuned the carb so now I’m very comfortable in doing such things. I’ll put new seals and gasket and what needed to be replaced on this saw, clean it and we’ll go from there. My focus is on arborist stuff, chainsaw is a bonus and this will be as far as I’ll go for chainsaws. Maybe I’ll collect some desirable saws along the way to fix. Definitely share more here and appreciate and respect all feedback from you guys!
