Stihl 051 AVE retire or rebuild? I have an 051 ave i was my late grandpa's saw. It starts when it wants .runs great when not in wood( it bogs in wood no matter were carb is set alot like 041carb thread) I am thinking of a rebuild new P&S and a carb rebuild, or just save my money and get a new saw for the bigger wood and retire the 051. Just looking for opinions just got a ms260pro and love the new saws. Also how much can the 51 be modded? If I rebuild it I will want to do some extras to it.
