Saw a listing for a 266 locally says starts and runs off choke but doesn't idle. Has old fuel and has been sitting for a while. Are these saws powerful enough to mill some 12" ash or maple possibly? Currently I run a ms290 for all my firewood needs and it is my only saw. The asking price has been tempted to give it a go. I would either keep the 290 or sell it for more than the asking price of the 266. Pretty handy and don't mind getting into the saw as a winter project in my workshop either. Not if parts are hard and expensive to get. Thanks.
