I took another look at the saw. The side cover is also cracked. You can see the adjuster screw bulging. It looks like the PO tightened the cover down without aligning the adjuster pin to the hole in the bar and cracked the cover.
I saw this saw on the side of the road near some garbage cans. I went to the door and asked the owner of the house if he wanted the saw. He gave it to me. I have Stihls with long bars and was looking for a small saw to buck trees I drop. I cut up trees for firewood.
Does anyone have a parts saw? I need a side and top cover.
