Did you pay 1500 for this saw? I think you have a hole in yer piston. also never trust a spark plug to stay tight, always tack weld them.I was just given a stihl 064 and I am having the same trouble, I pull and pull on the starter cord, and not even a pop. I checked the belt, pulled the muffler off and put in a new spark plug. A Bosch BTW. And still nothing....
I need this saw because I am going to tackle my first 48 inch oak on the weekend. The tree needs to come down as it is infested with ants and limbs are starting to fall off.
