My woods saws get around 600-700 hrs a season then its time for crank seals carb work etc. and noone has a good warranty except dolmar. one of the reasons I'm kind of bent on Stihl is their poor warranty and the fact that their saws are set to lean out of the box, seems kind of mean to set the saw to burn up then give a 3 month warranty. the last 6 saws I've purchased I had to spend another 40.00 each to get the carb worked on so I could get enough fuel on the high side. But while running the 440 the other day I was thinking what a good rig that series has been for well 14 years now, Ijust saying the 7900 hasnt got there yet, not to worry though Dan, I'll be getting a 7900 from you jusrt as soon as I get that 346 in my hooks, any timeframe I have a headleaner to peice out need that chainspeed.
