Mowerfreak, I understand what you are talking about re-metal shim when I went to tighten the pull cord. Both mowers when I picked them up needed to be tightened and I did this after I read your post so I was very careful to keep my eye out. Once you know It is quite easy and it makes the design much more effective when tight. Now I just need to find why I have no spark. I did get one to fire with a quick squirt of starter fluid but no spark now.
