I just bought a new Toro 721E and I love it. However, I noticed that my cable has melted due to the heat of the exhaust. I believe it is from the heat of the handle that it rests on when the control bar is released and the cable has slack. Fortunately the cable is metal wire covered by plastic but this is a poor design OR my tension is off. If the cable is tightened to keep it off the metal handle bar then I think this will be too tight. Any suggestions or similar experience? See pics for further clarification.
