The low is just throttle response to get it to transition to high. That seems low for the low setting and extremely high for the high setting. Watch this video about how to tune a 7900 correctly. http://www.arboristsite.com/chainsaw/147465.htm OH, remove the stops, they may not let you go far enough!
