So picked up this MS291with a few other saws that needed work. It was darn close to new. Heard a rattle when pulled starter and after tearing it down found that plate on cylinder/crankcase fell off. Also found very little holds it on. In fact it looks like it’s glued on. The cylinder and piston are like new. The build quality is piss poor. Shame really for what this saw sells for new. Can’t imagine why you wouldn’t use fasteners to hold in place. Cutting corners. Included an older Stihl cylinder for reference.
