Man.....that first picture looks like a brand new mower!!! So who did the "winter tuneup"???? And did it look like the second picture "before the winter tuneup"???? And I thought I was anal about having my mower look clean.....maybe both of us need some serious therapy:0)
But, I've always said(about my automobile/truck engines....which I also clean regularly)...."a clean engine is a happy engine"!!! Also, even my mechanic when he works on my 1995 Silverado Z71(that has over 230K miles) can't believe how "new" my engine looks!!! I'm a firm believer that the worst enemy an automobile engine has is a dirt/grime/oil/etc. "buildup" all over it that makes the cooling system hard-pressed to keep it from overheating. Of course my mechanic seems to agree with that philosophy.
I've always kidded around that the dirt is what holds my cars together:wink:
