Hi Grumpy
Great explanation! I think one of you replies to me you said that the engine could have been over heated. I wanted to tell you when I got the mower the whole cylinder head was incased in old grass just cake in between the cooling fins. I power washed the engine before I did anything. So I wonder if was heat that cause the whole issue with valve guide? I haven't found anything that would have cause the guide to come out.
Thanks
Mike
