Just wondering if anyone here has had this problem. I bought an MS260 Pro in April, and felt like it was under powered compared to my Shindaiwa 488. Because of that, I didn't use it much. Recently I had problems with one of my 488's and pulled out the 260 pro. It ran about 15 min and quit, so I brought it back to the dealer I bought it from. The saw still has the original chain on it and has not burned two tanks of fuel, but he tells me the saw is burnt due to over reving. I've been running Shindawia saws for years and have never had one burn up from "over reving". Any comments would be appreciated.
