while cutting word the other day I saw a bolt on the ground . I stopped the saw and found that it did come from the husky / one of the 2 bolts holding the muffler in place had worked its way out. I put it back in and it kept working its way out after a few mins of operation. since this chainsaw is 10years old I am ready to replace it . ,I ordered the parts from Baileys. does anyone have the procedure . I ordered the muffler assemby along with face plate, gasket and two bolts along with spark arrester screen.
