Broken air cleaner case assembly.

With the broken air cleaner assembly, the cover could not latch fully and let in some debris. I could have only replaced the assembly but as it was my annual maintenance time I decide to replace the whole system. This was a good idea because there was some debris throughout the area for the carburetor intake area, fine dust/grass particles. Easy to accomplish, just be sure you have a torque wrench for the gasket bolts. Over-all moderate (because of torque settings) but ereplacement Parts cam through (again) with everything I needed.
