Seen this more then once now. So for folks buying saws in and around MI. = There is something up there in MI folks cut that does cause mag rot under the clutch covers on the side of the mag cases. Friend told me about it once I started getting saws from there in MI with mag rot and wondered why. John showed me nice jonsered saws that was starting to rot too from MI. What did you say they cut up there doing this? =all those saws I showed you were covered in pine sap/sawdust. Under the right environment high humidity pine is acidic. Farmer measured the amount of free acid produced by various woods under controlled conditions at intervals up to two years. For all timbers examined, including oak, Douglas fir, Sitka spruce, beech, birch, obeche and Parana pine, there was a progressive increase in free acid. More than 90% of the acid was volatile and was identified chemically and chromatographically as acetic acid. I had thought it was only a south thing from cutting palms etc. But isnt. MI has something they cut up there that does it too. So now check under covers on any MI saws going to buy. UPDATE guys in ME seeing this too. *****************************************************
