Oh happy day. I did what you guys suggested (in hte off topic thread) about my green swimming pool and it worked. It is allmost as clear as a glass of cold spring water. bad news, my better wont start, one click, is that always the battery? So okay, I proceed to my yards that I can use my Z on. It quit about 150 yards away from the street and my truck, not to mention down a very steep hill. At first I tought it was out of fuel (and I still think it was) but I switched to a full tank and it ran for about 5 min and stopped. I came home to regroup, but I am down to my 21" and a John Deere L 100 residential I have had for year. I might just strart drinking beer.
