First post here even though I've used this site in the past when reading about saw repairs and tuning. I've been wanting to buy a Stihl saw that needed repairs that I can do myself for cheap, mainly because I need the power to cut thru big mesquite trees here in South TX. I picked up this 066 for $130 dollars yesterday. It has a scored up piston and the bar is too rusty to service. I'm intending to put a Meteor piston/cylinder kit in it, go thru the carb, and put a 24" bar on it. I'll use it and if it's too big, probably sell/trade it off for a new MS250 which is more than likely better suited for what my uses are.
