Chain saw has compression from just pulling rope, have not done any diagnostic on chainsaw! Do not have much info about the saw, it has been sitting on shelf for years and never got around to fixing it, figured its great for parts as it’s barely seen any wood in its life time. If you need pictures with the sprocket cover off I’ll be able to get you some if needed, I plan to add them just got some quick pictures to get the listing started! Thanks and reach out if need to!
