My son is with a Forest Service handcrew on the Waldo Canyon fire in Colorado. He sent me an e-mail last night saying they are having issues with their saws due to the altitude (>7,500'). I believe that they run Stihl 460 Magnums. He did not specify what the issues were, but I suspect they are down on power, idling roughly and fouling plugs.
My question is: Can the idle screws be adjusted for high altitude or do those models have "smart carb" technology that compensates automatically.
Any ideas would be most helpful.
