Just picked up a small homelite 180 classic with a 14" bar. Pretty cool saw, kind of like my dads(homelite super 2 with 16"bar) and i was just curios if any of you knew what kind of mixture it takes? also when i shut it off without the bar on the clutch likes to spin and make a weird noise that sounds like the bearings or something like that. Any information would be greatly appreciated. thanks in advance.
